<h2>HLR Telecommunications Definition</h2>

<p>HLR stands for &quot;Home Location Register,&quot; and it is a crucial component in telecommunications networks, specifically in the context of mobile and cellular communication systems. The HLR is a database that stores essential information about subscribers who are part of a mobile network.</p>

<p>In a mobile network, each subscriber is associated with a home location, which is essentially the network operator they are subscribed to. The HLR contains various subscriber-related data, including subscriber and location info, subscriber services and ststus, romaning and security info.</p>

<p>When a call, text message, or data request is made to a subscriber&#39;s mobile number, the network consults the HLR to determine the subscriber&#39;s location and whether they are reachable. This information is crucial for the network to properly route calls, messages, and data to the subscriber&#39;s current location.</p>

<p>The HLR database includes:</p>

<ul>
	<li>International Mobile Subscriber Identity (IMSI)</li>
	<li>The phone number associated with the Mobile Subscriber Integrated Services Digital Network (the MSISDN)</li>
	<li>Account status</li>
	<li>Call divert settings</li>
	<li>Services requested by or rendered to the corresponding subscriber</li>
	<li>General packet radio service settings of the subscriber</li>
	<li>Last known location</li>
</ul>

<p>As long as the subscriber remains connected with the mobile network operator, the data can be easily accessed.</p>

<p>The International Mobile Subscriber Identity (IMSI) is the information that identifies each Subscriber Identity Module (SIM)</p>

<p>The Mobile Subscriber Integrated Services Digital Network (MSISDN) is the phone number you use to connect with a specific mobile user. The primary number is used for making and receiving voice calls and SMS. You can use a second for fax and data communication.</p>

<h2>Functions of HLR in Telecom</h2>

<p>HLR in telecom serves as the database for subscriber parameters. It includes customer ID, number, billing details, and the current recharge of the prepaid user. Moreover, it is the master database of all the subscribers to the GSM PLMN. The main database that contains permanent information about the subscriber&mdash;including the type tech with 2G, 3G, 4G, or 5G&mdash;is in GSM.</p>

<p>It is a component of 2G and 3G. However, 4G networks have a separate database called Home Subscriber Service (HSS), and 5G makes use of Unified Data Management (UDM) to manage network user data in a single, centralized element. This technology is identical to the 4G&#39;s HSS&mdash;the difference is that it&#39;s cloud-native and particularly intended for 5G.</p>

<p>As an important component for every subscriber, in mobile communication it is a database of every active customer of a mobile network. The Message Switching Center (MSC) uses the network&rsquo;s database to identify the subscriber and authorize access to services. It also determines what to charge for which service and how to route the transmission to and from devices. When a contract ends with a carrier, the subscriber is removed, cutting access to the network.</p>

<p>If a subscriber belongs to a mobile network operator&rsquo;s roaming partner, the databases don&rsquo;t include information about the subscriber in these cases. When the local MSC checks with its Visitor Location Register (VLR), it requests the subscriber information from the home network. The VLR then confirms whether the device is allowed to attach to the network and verify the SIM. The database sends information to the VLR regarding what service the particular SIM can use, and the VLR temporarily stores the information.</p>


A home location register (HLR) refers to subscribers that are authorized to use a global system for a mobile (GSM) core network. HLR is a database that contains subscriber information.

<p>The system routes calls based on data from the customer, as well as language, contact channel, and type of query. The query can be in the form of an email, a voice call, or any other chat channel.&nbsp;</p>

<p>Intelligent Call Routing (ICR) is the act of managing inbound calls and directing them to the most suitable agent.&nbsp;<a href="https://dexatel.com/blog/cloud-contact-center-provider/" title="Cloud Contact Center Providers">Cloud contact centers</a> use intelligent routing in conjunction with&nbsp;<a href="https://dexatel.com/glossary/sip-trunking/" title="What is Sip Trunking?">SIP trunking</a> to receive calls over the internet.&nbsp;</p>

<h2>How Does It Work?</h2>

<p>Intelligent call routing, like&nbsp;<a href="https://dexatel.com/glossary/attribute-based-routing/" title="What is Attribute Based Routing?">attribute-based</a>, uses various data to determine where to send calls for the best outcome&nbsp;</p>

<h3>Caller Input</h3>

<p>An Interactive Voice Response (IVR) system allows callers to provide the key information required for proper routing. By using this information, the ICR system routes the call based on several factors. These include caller intent and the company&rsquo;s priority in handling the call.&nbsp;</p>

<h3>Current Caller Data</h3>

<p>The data collection tools that ICR software features include Automatic Number Identification (ANI). It is a system that identifies the phone numbers that the calls are coming from. Another data-gathering tool is the Dialed Number Identification Service (DNIS). This determines where to direct the call.</p>

<h3>Historical Caller Data</h3>

<p>After an ICR system identifies a caller, it automatically extracts information about the caller from the organization&rsquo;s database. This data can include the caller&rsquo;s purchase history, account status, and service programs. It can also contain specific details that can be useful for the correct interpretation of the caller&rsquo;s intent.&nbsp;</p>

<h2>Benefits of Intelligent Call Routing</h2>

<h3>Less Waiting Times</h3>

<p>Intelligent call routing solutions distribute incoming calls to the most suitable agents based on factors like skills, workload, and availability. The system directs calls to specific agents who know how to address the callers&rsquo; specific needs. This minimizes the time callers spend on hold, leading to a better customer experience.&nbsp;</p>

<h3>Fewer Abandoned Calls</h3>

<p>An effective ICR system reduces the number of abandoned calls, where frustrated callers hang up because of long waiting times. By instantly linking customers to appropriate agents, companies can minimize call abandonment rates. They also boost customer retention and prevent missed opportunities.</p>

<h3>Cost-Effective</h3>

<p>Robust call routing plays a major role in cutting costs, and it does so through optimum resource allocation. By transferring callers to the right agents, the system minimizes idle time and maximizes team productivity. It can also help companies avoid understaffing or overstaffing issues, resulting in more cost-effectiveness.&nbsp;</p>

<h3>Easier Access</h3>

<p>ICR allows agents to receive incoming calls from anywhere, including the office, home, or a different time zone. This presents better accessibility for both callers and agents, allowing companies to offer 24/7 support and cater to global audiences.&nbsp;</p>

<h3>Faster Outcomes</h3>

<p>By directing calls to agents who have the relevant knowledge, customers can receive faster and more accurate answers to their questions. It won&#39;t be necessary to transfer callers from one agent to another. This leads to quicker problem-solving and a more positive experience for customers.&nbsp;</p>

<h3>Increased Efficiency</h3>

<p>ICR boosts individual agent efficiency as it connects callers to agents whose skills align with the nature of the calls. It also fosters collaboration within the support team. Agents can share insights and information more effectively, improving problem resolution and customer service capabilities.&nbsp;</p>

<h2>When Does a Business Need Intelligent Routing?</h2>

<p>There are certain signs that indicate the need for an intelligent call-routing system. It&rsquo;s common for many businesses to handle large volumes of inbound calls. Customers calling companies can sometimes report one of several issues when trying to contact a support agent. These include:</p>

<ul>
	<li>
	<p>Long waiting times</p>
	</li>
	<li>
	<p>Multiple transfers from department to department</p>
	</li>
	<li>
	<p>Difficulty pinpointing the most appropriate agent who can deal with the specific case</p>
	</li>
	<li>
	<p>Spending too much time trying to understand the issue at hand</p>
	</li>
</ul>

<p>In cases like these, it&rsquo;s easy for businesses to lose track of caller intent. What follows is a decrease in customer satisfaction due to frustration and unresolved cases. The solution is to invest in up-to-date artificial intelligence (AI) call-routing software.</p>

<h2>How to Migrate to an Intelligent Routing System</h2>

<p>Transitioning from an automatic call distribution (ACD) to an ICR system involves taking a number of key measures.&nbsp;</p>

<p>1. Set goals for the ICR platform and determine how much you need to improve the customer and agent experience.</p>

<p>2.&nbsp;Segment your audience and choose what services you want to offer each segment.&nbsp;</p>

<p>3. Develop strategies for your communication channels and network them across the integrated ICR software for a seamless experience.</p>

<p>4. Evaluate your customer support team&#39;s skills, find areas to improve, and prioritize proficiency levels for a good customer experience.</p>

<p>5. Match agent skills to suitable resources for each call and have backup resources when the initial agent is unavailable</p>


Intelligent routing (IR), also known as skills-based routing, is a technology that call centers use to connect customers to the right agent who can address their needs. It helps boost operational efficiency and enhance the customer experience.

Intelligent Routing

<p>Physical wires made it possible to have long-distance telephone communication. As telephone communication progressed, wired networks multiplied in quantity. But, the wires had two major problems.</p>

<ol>
	<li>The cables&mdash;especially longer wires&mdash;were prone to physical damage in case of disasters or emergencies; fixing them was not an easy task</li>
	<li>The wires were expensive to buy and maintain, which was unprofitable for businesses</li>
</ol>

<p>Long-distance phone calls in numerous business domains are more urgent than ever. With SIP trunking, we can now use the internet to transfer voice and video messages for longer distances&mdash;it significantly cuts down the cost of phone calls.</p>

<p>For a better understanding of call trunking, let&#39;s elaborate on SIP, PBX, and Trunk, and what their functions are.</p>

<h2>What Is SIP?</h2>

<p>Session Initiation Protocol (SIP) is an application layer protocol that uses an internet connection to transfer voice or video messages from one point to another. It replaces traditional wires with virtual channels that allow two ends of PBX (Private Branch Exchange Phone System) to connect. Simply put, SIP is the technology that creates, modifies, and terminates sessions with one or more parties in an IP network, whether a two-way call or a multi-party conference call.</p>

<h2>What Is Trunk?</h2>

<p>SIP transfers voice or video signals to a PBX, which in turn transfers them to the other end. The routes through which the internet protocol transfers the voice or video signals are called trunks&mdash;they are the roads that signals take to get from point A to point B. Trunks also have channels that carry incoming and outgoing calls.</p>

<h2>What Is PBX?</h2>

<p>A Private Branch Exchange System (PBX) allows multiple phones to communicate interchangeably&mdash;it connects with local telephone lines to make internal communication possible. This means that every phone line in an organization can make internal calls thanks to a PBX. The PBX for SIP trunking carries out the same functions; the only difference is that it uses cloud-based PBX instead of physical hardware.</p>

<h2>Best SIP Providers</h2>

<p>Using the right SIP service empowers business communication, and these leading companies are the top SIP trunk providers worldwide. Offering a variety of products and pricing models, these SIP trunk providing companies satisfy various business needs and purposes.</p>

</ul>

<h2>SIP Trunk Pricing: How To Choose the Best Option?</h2>

<p>Trunk services come in a variety of pricing options&mdash;the cost differs from country to country and is based on case-by-case. Several factors determine the cost.</p>

<ul>
	<li>Establishing your business needs to choose the features you want to include</li>
	<li>Deciding which package is best suited for your needs and your budget (monthly or annual subscriptions)</li>
	<li>Recognizing the equipment required for SIP trunks. If you already have hosted PBX, the cost will be cheaper</li>
	<li>Understanding the different pricing options based on your location</li>
	<li>Learning about SIP providers like Plivio that redeem free credits and offer pay-as-you-go options or volume discount</li>
	<li>Reaching out to your company of choice&rsquo;s sales department to walk you through the purchase process</li>
</ul>

<h2>Hosted PBX Vs. SIP Trunking</h2>

<p>Hosted PBX and SIP trunking models of business phone systems and virtual communication. On one hand, SIP trunking is a gateway that directly connects an existing on-site PBX system to the virtual network. On the other hand, hosted PBX is an offsite business VoIP phone system managed by the third-party Internet Telephony Service Provider (ITSP).</p>

<p>Let&rsquo;s say your company has 100 employees and they need to be able to call each other. Ideally, they shouldn&rsquo;t have 100 different phone numbers. Rather, they&rsquo;d have extension numbers and the ability to forward calls. The PBX is the hardware that links between the company&rsquo;s internal extension numbers, as well as customers and extension numbers.</p>

<p>As for external communication, the call first reaches the PBX, which sends it to the Public Switched Telephone Network (PSTN), and finally reaches the client.</p>

<p>Hosted PBX is essentially the same as PBX, but the equipment is hosted off-site by another company. PBX is expensive hardware, whereas hosted PBX is a relatively affordable option.</p>

<p>Hosted PBX provides:</p>

<ul>
	<li>Regular maintenance</li>
	<li>Call features (call recordings, voicemail, transferring calls, and so on)</li>
	<li>Software upgrades and service troubleshooting</li>
</ul>

<p>If you already have hosted PBX, you can move your business communication to the cloud through a VoIP SIP provider.</p>

<p>SIP trunk provides:</p>

<ul>
	<li>Advanced phone system features like long-distance calling</li>
	<li>Better call quality with relatively affordable cost</li>
</ul>

<p>Which Type of Business Phone System Should You Install? - H2</p>

<p>Deciding on the right phone system greatly depends on your business needs, infrastructure, and working methods.</p>

<p>Larger enterprises usually opt for SIP trunking. If your company deals with international calls, involves more virtual work, high volume of calls, and has expansion potential, SIP trunking is the right choice for you.</p>

<p>Hosted PBX is ideal for small and medium-sized businesses that don&#39;t have a significant volume of phone calls.</p>

<h2>SIP Trunk Vs. Elastic SIP Trunk</h2>

<p>Besides hosted PBX and SIP trunking, businesses must also choose between elastic SIP trunk and SIP trunk services.</p>

<p>Elastic SIP trunking is a more advanced option of cloud communication that enables users to have more control over their needs. For instance, if your company faces an expected peak at a specific time of the year, you can pay-as-you-go instead of a monthly subscription.</p>

<p>This way, elastic SIP trunking:</p>

<ul>
	<li>Reduce costs</li>
	<li>Provides calling flexibility</li>
	<li>Meets fluctuating business needs</li>
</ul>


Session Initial Protocol Trunking, also known as SIP trunking is the process of sending and receiving voice or video calls via the internet. It is similar to a traditional phone system minus the cables or physical network connections—virtual SIP lines have replaced them all.

SIP trunking allows you to make and receive calls using the internet through cloud-based systems.

SIP trunking is a way of sending voice or video signals to different points using a cloud-based PBX.

SIP Trunking?

SIP Trunking

<p>The exchange mainly takes place between&nbsp;<a href="https://dexatel.com/glossary/smsc/" title="What is SMSC?">Short Message Service Centers</a> (SMSCs). Being a level-7 TCP/IP protocol, SMPP enables the speedy delivery of text messages.</p>

<p>The system serves as a language for cellular networks to transmit&nbsp;SMS communications. It controls how <a href="https://smppcenter.com/kb/what-is-esme-external-short-messaging-entity/" title="What is ESME (External Short Messaging Entity)?">External Short Message Entities (ESMEs)</a>, like&nbsp;business messaging platforms and Internet of Things devices, communicate through mobile phones.</p>

<h2>The Different Versions&nbsp;</h2>

<p>There are three various versions of SMPP: v3.3, v3.4, and v5.0. The oldest version is SMPP v3.3. Newer versions include new types of sessions, new <a href="https://www.geeksforgeeks.org/protocol-data-unit-pdu/" title="Protocol Data Unit (PDU)">PDU (Protocol Data Unit) parameters</a>, and support for extra technologies. Each session must specify the version the ESME uses, as it determines the interaction between the two entities.</p>

<h2>How Does It Work?</h2>

<p>When a mobile phone or SMS-enabled application needs to deliver a text to another device, it activates an SMPP session. The session takes place via the mobile carrier&rsquo;s message service center (SMSC). While the session is in process, the two endpoints communicate via the SMSC, which defines which entity is relaying the messages.</p>

<p>It also determines whether to accept or reject the transmission. As an element of&nbsp;<a href="https://dexatel.com/glossary/intelligent-routing/" title="What is Intelligent Routing?">intelligent routing</a>, it allows for dynamic routing decisions according to real-time network conditions and delivery needs.</p>

<p>Should one of the entities require an SMS gateway to communicate, the gateway serves as a mediator, too. It transmits data to and from the SMSC. If the Message Center rejects the transmission, it sends an error code to specify the issue. This can be an invalid request, destination, message ID, or text length.</p>

<p><a href="https://dexatel.com/glossary/mobile-network-operator/" title="What is MNO?">Mobile network operators</a> sometimes use SMPP in conjunction with&nbsp;<a href="https://dexatel.com/glossary/sip-trunking/" title="What is Sip Trunking?">SIP trunking</a> to enable businesses to send messages over IP networks. This facilitates the integration of SMS with VoIP (Voice over Internet Protocol) systems.</p>

<h3>Types of Sessions</h3>

<p>There are three different types of sessions that an ESME initiates. A transmitter session is for sending&nbsp;<a href="https://dexatel.com/glossary/mobile-terminated/" title="What is Mobile Terminated?">mobile terminated</a> messages to a mobile device. Receiver sessions are those that ESMEs activate to receive mobile-originated messages.</p>

<p>As for transceiver sessions, they support both sending and receiving messages. This type of session isn&rsquo;t available with v3.3. An outbind session, on the other hand, is one that the SMSC initiates.</p>

<h3>Protocol Data Unit</h3>

<p>At the beginning of each session, a bind command defines what type of interaction will occur. To activate a transmitter session, for example, the SMSC delivers a PDU containing the command bind_transmitter. This PDU, which consists of requests and responses, also includes the ESME&rsquo;s type, passcode, and identification. Moreover, the PDU specifies the SMPP version that the ESME is utilizing and determines where the SMS communication is coming from.</p>

<h2>Benefits of SMPP</h2>

<ul>
	<li>
	<p><strong>Efficiency</strong>: Designed with high performance in mind, SMPP allows for the fast transmission of SMS messages</p>
	</li>
	<li>
	<p><strong>Reliability</strong>: By providing delivery confirmation and solid handling of errors, it guarantees that messages reach their intended destination</p>
	</li>
	<li>
	<p><strong>Scalability</strong>: An SMPP server can handle messages in large volumes, making it ideal for companies with considerable messaging needs</p>
	</li>
	<li>
	<p><a href="https://dexatel.com/glossary/real-time-communications/" title="What is RTC?"><strong>Real-time communication</strong></a>: It facilitates real-time reporting and delivery of messages, which is vital for time-sensitive communication</p>
	</li>
	<li>
	<p><strong>Security</strong>: It offers secure messaging, safeguarding sensitive information during delivery</p>
	</li>
	<li>
	<p><strong>Customization</strong>: Users can configure the system to fit certain requirements, making it versatile for different messaging software</p>
	</li>
</ul>

<h2>What Is It Used for?</h2>

<h3>Business Messaging</h3>

<p>Businesses use an SMPP protocol to deliver messages from an&nbsp;SMS platform to individual contacts or a whole group of customers. These include&nbsp;promotional messages, customer support,&nbsp;appointment reminders, feedback requests, and&nbsp;<a href="https://dexatel.com/glossary/otp-sms/" title="What is OTP?">OTP verification</a>.</p>

<h3>Cellular IoT&nbsp;</h3>

<p>IoT (Internet of Things) devices like smart thermostats, smoke alarms, and home security systems use SMPP to transmit notifications. These can be about energy consumption, motion detection, or other critical alerts. When a smart alarm system detects a fire, for example, it uses the SMPP to immediately inform the homeowner. The alert can sometimes include a link to the smart security camera.</p>


SMPP (Short Message Peer-to-Peer) is a protocol the telecommunications industry uses to exchange SMS texts over the internet.

SMPP?

SMPP

<p>Businesses can deploy applications without the need to develop the backend infrastructure. They only need to manage the data while the provider handles storage, servers, hardware, and other technical aspects of the solution. Communications platforms enable the customization of communications stack. Rather than buying a solution that comes with predefined functions, users can integrate their preferred communication channels with their existing tools. Studies reveal that the CPaaS market is expected to reach&nbsp;<a href="https://www.mordorintelligence.com/industry-reports/communication-platform-as-a-service-cpaas-market" target="_blank">$61.59 billion by 2025</a>.</p>

<h2>How Does a Communication Platform as a Service Work?</h2>

<p>CPaaS technology integrates messaging features into existing software by using a communication application programming interface (API). The Communications APIs serve as a software intermediary that translates between two endpoints, allowing them to interact with each other.&nbsp;</p>

<p>Using CPaaS systems may require the experience of developers who understand the technical aspects of developing apps that make use of communication APIs. It&rsquo;s also crucial to have devices or software that are compatible with communications API endpoints. Many businesses use an in-house IT department to handle these software development kits, while others prefer outsourcing the process to systems integrators.&nbsp;</p>

<h2>CPaaS Vs. UCaaS</h2>

<p>Although both CPaaS and UCaaS are cloud-based and provide a feature-rich communications stack, they are not the same. The differences lie in the way they deliver business messaging solutions. A CPaaS platform utilizes communication APIs to select and develop necessary features. UCaaS (unified communications as a service) combines communication services into one ready-to-go platform.&nbsp;</p>

<p>Integrating UCaaS into an application is not possible like it is with the CPaaS model. Instead, businesses use it in conjunction with their existing applications. While UCaaS is suitable for companies that prefer a more straightforward platform, it&#39;s not as efficient and flexible as a CPaaS service.&nbsp;</p>

<h2>What Does a Communication Platform Do?</h2>

<h3>SMS Texting</h3>

<p>By building <a href="https://dexatel.com/blog/sms-communications/">SMS communication</a> into software, businesses can deliver alerts, reminders, and other notifications from their company phone number. They can also set up&nbsp;<a href="https://dexatel.com/features/two-way-sms/">two-way messaging</a> to make it possible for customers to respond. Using an SMS API or an SMS platform enables automation, group texting, checking the delivery status of messages, and more.</p>

<h3>Outbound Voice Calling</h3>

<p>Sales and marketing teams can incorporate outbound calls into their cloud-based communications infrastructure through voice APIs. This makes it possible to scale operations up or down as needed. Moreover, using voice APIs for outbound calls enhances adaptability to shifting environments and facilitates adjusting call capacity.&nbsp;</p>

<h3>Inbound Call Routing</h3>

<p>With the help of webhooks, routing inbound calls can be an easy process. An incoming call triggers a webhook, causing the system to carry out a set of actions to process the call. These involve routing the call to a certain agent, making it easy to streamline and customize your call-handling methods.</p>

<h3>SIP Trunking</h3>

<p>SIP (Session Initiation Protocol) trunking is how IP-based communications infrastructures get connectivity. The flexibility of on-demand SIP trunking gives businesses the ability to improve or reduce their call capacity. Depending on the communications service provider you choose, you&rsquo;ll get different features and communication capabilities with SIP trunking.</p>

<h3>Social Media Messaging</h3>

<p>Social media and instant messaging apps like WhatsApp and Instagram are excellent for driving customer engagement. They are useful for creating rich communication experiences. WhatsApp, for example, can consolidate various CPaaS functions. These cloud-based services include sending and receiving multimedia files, sharing locations, and much more.</p>

<h3>Multimedia and Video Calling</h3>

<p>Besides supporting automation and other functions, SMS APIs also enable sending and receiving videos, images, and other media. Not all CPaaS providers provide MMS as part of their features. Others offer various options for international phone numbers, MMS, file sizes, conversions, and media storage.</p>

<h3>Phone Number Masking</h3>

<p>Number masking allows for connecting two parties, like a customer and a support agent, without exposing their phone numbers. It is an effective way of safeguarding customers&rsquo; identities, protecting sensitive information, and guaranteeing the safety and privacy of everyone involved. This way, only the CPaaS vendor gets access to the call participants&rsquo; numbers.</p>

<h3>WebRTC-Based Calling</h3>

<p>WebRTC refers to an open framework that uses APIs to facilitate <a href="https://dexatel.com/glossary/real-time-communications/">real-time communications</a> (RTC) in mobile apps and web browsers. Certain communication platforms feature WebRTC solutions that businesses can use to integrate voice and video messaging into their setups. This allows them to include features like call recording, video conferencing, call queues, and more.</p>

<h2>Benefits of CPaaS</h2>

<h3>Inexpensive and Cost-Efficient</h3>

<p>As cloud-based communications solutions, CPaaS software can help save a great deal of money down the line. Businesses using the software don&rsquo;t need to spend resources on developing and maintaining infrastructure. They&rsquo;ll only pay for the services they use or a subscription fee, depending on the pricing model the cloud-based platform offers.</p>

<h3>More Secure</h3>

<p>With measures like encryption, <a href="https://dexatel.com/blog/two-factor-authentication/">two-factor authentication</a>, and instant fraud alerts, a communication platform can provide an extra layer of security. This enhanced level of security helps companies reduce risks effectively, safeguard sensitive data, and foster a sense of trust among customers.</p>

<h3>Ideal for Customer Service and Technical Support</h3>

<p>Communication platforms enable real-time communication between agents and customers without the need to leave the application or contact various numbers. This makes it a valuable asset for establishing a strong customer base. Clients can get answers as quickly and efficiently as possible, while technical support teams resolve issues instantly.</p>

<h3>Customizable and Integratable</h3>

<p>The customizable nature of communication platforms suits unique business needs.

And since the software uses an API, a company can easily integrate custom applications into it without compromising the integrity of the existing application.</p>

<h3>Scalable</h3>

<p>Besides being customizable and easy to integrate, CPaaS solutions also offer full scalability. For example, if a business plans on adding a voice channel later, it can do so with no hassle. It can also remove an obsolete function without a problem. This flexibility makes it possible for companies to scale their business communications to meet the changing needs of their audience and industry.&nbsp;</p>

<h3>Easy to Implement</h3>

<p>By using APIs, businesses can quickly build and implement real-time customer communication channels like voice, messaging, and video chat. They can deploy these features into mobile, web-based, as well as enterprise applications.

<h3>Customer Service</h3>

<h3>Security&nbsp;</h3>

<p>Communication platforms can be useful for protecting sensitive information against fraud, breaches, and other security risks.

<p>A2P messaging involves the use of a software application to send or respond to text messages. This is useful for various types of messages such as reminders, two-factor authentication codes, and marketing messages. It is an increasingly common tool for businesses that want to reach out to their audience more efficiently without expecting a reply. Many website chatbots are also known to make use of application-to-person messaging.</p>

<h2>Understanding A2P Messaging in Depth</h2>

<p>Text messaging is a powerful communication tool that leverages the ubiquity of mobile devices to deliver messages directly from applications to individuals. It is a key component of many business operations, enabling seamless and efficient communication with customers, employees, and other stakeholders.</p>

<p>The technical process of A2P messaging involves sending messages from an application, through an SMS gateway, to a mobile user. The gateway translates the message into a format that can be understood by the mobile network, which then delivers the message to the recipient&#39;s device. This process allows for high-volume, automated messaging, making it an ideal solution for businesses that need to communicate with large audiences.</p>

<h3>How A2P Texting Works?</h3>

<p>Businesses use application to person messaging to communicate with consumers, authenticate users, and deliver time-sensitive alerts in three technical modes:</p>

<ol>
	<li>Through a web-based application or software that directly sends mass texts by importing receivers&rsquo; numbers</li>
	<li>Through an API when businesses integrate communication solutions into their existing CRMs or any other type of system</li>
	<li>Through ready-made integrations on popular platforms such as downloading the Dexatel plugin on WordPress</li>
</ol>

<p>In the first mode, businesses use a web-based application or software to send mass texts. They import the receivers&#39; phone numbers into the system, create the message, and then send it out. This is a great way for businesses to send out marketing messages, appointment reminders, and other types of one-time messages.</p>

<p>In the second mode, businesses integrate communication solutions into their existing systems using an API. This allows businesses to automate the sending of SMS based on certain triggers or events. For example, a business could set up their system to automatically send a text message to a customer when their order has been shipped.</p>

<p>In the third mode, businesses use ready-made integrations on popular platforms. For example, a business could download the Dexatel plugin on WordPress to enable A2P messaging. This is a convenient option for businesses that already use these platforms for their operations.</p>

What is A2P Messaging? | Glossary Definition of Application-to-Person SMS

A2P?

<p>OTP SMS is one of the most popular mechanisms used by companies to make sure that an authorized person generated the login request.</p>

<p>Once users enter their username and password, they receive an OTP on their mobile phones. The message contains a code, usually four to six digits that&#39;s valid for one-time use&mdash;some are even time-based one-time passwords (TOTP) that expire within a minute. Users have to enter the code quickly to proceed with logging in. This way, an OTP message guarantees that the user logging in is authorized by the account holder.</p>

<h2>Trending Use Cases OF OPT SMS</h2>

<ul>
	<li>Two-factor authentication for login authorization</li>
	<li>Phone number verification for new registrations</li>
	<li>Account recovery for password resets</li>
	<li>Payment confirmation for making purchases</li>
</ul>

<h2>Who Needs an OTP SMS Service?</h2>

<p>With <a href="https://securityboulevard.com/2020/12/cybercrime-expected-to-rise-at-an-unprecedented-rate-in-2021/" target="_blank" title="Cybercrime Expected to Rise At an Unprecedented Rate in 2021">increasing cyber crimes and user data theft</a>, companies are prioritizing substantial account security mechanisms to minimize these instances. Many corporations like Google and Facebook have installed two-step authentication to protect users against unauthorized logins. The OTP text message technology has significantly simplified this process.</p>

<p>Online identity theft is a massive problem that&#39;s only growing in its magnitude, especially with more people posting sensitive personal information on the web. Nearly 15 million US citizens are victims of cyber-attacks annually, resulting in a cumulative loss of almost $50 billion. Statistically speaking, this puts over 100 million people in the US at risk of losing their data.</p>

<p>Enabling the SMS OTP verification process offers additional protection to users from hackers when logging in to a website. Nowadays, this isn&#39;t just a wise decision&mdash;it&#39;s an essential step to take. If you&#39;re running a website that stores sensitive user information, OTP verification offers additional security to your account holders. Not only is this service affordable, but it also builds trust with your customers.</p>

<h2>Examples of OTP</h2>

<p>While online OTP verification is optional, many companies have chosen to set it as a default step during the login process. Most of the businesses who have decided to do this deal with sensitive operations like online payment portals operated by banks or other financial service providers. Even email service providers like Gmail as well as social media platforms like Facebook implement OTP services for an extra layer of security.</p>

<p>Let&#39;s elaborate on how world-class giants secure their users&#39; data with SMS.</p>

<h3>Gmail SMS OTP Verification</h3>

<p>Google claims it&#39;s very easy to get your account password stolen, which is why they encourage Gmail users to add the two-step OTP verification on their email accounts to prevent unauthorized access. The OTP text service is both fast and free to use. As soon as users log in to their Gmail account from an unauthorized device, they receive an SMS with a code, which users need to enter in order to access their account.</p>

<h3>Facebook OTP SMS Verification</h3>

<p>While Facebook doesn&#39;t demand OTP verification, they still recommend using it for safety. Users can provide their registered mobile phone number to Facebook and enable two-step verification. This way, when they log in, the social media platform sends a six-digit OTP verification code for users to proceed with the login. If users don&#39;t receive the code, they can send an SMS to 32665 to get the code for free.</p>

<h3>Amazon OTP Message</h3>

<p>Amazon uses OTP text messages as part of its two-step verification process. Customers can choose to receive their password through a voice call or with an Amazon authenticator app. Since many customers use their personal devices to log in, Amazon allows the option to register devices so that two-step verification is not required every time a user logs in.</p>

<p>Some devices offered by Amazon also require OTP authentication even though they do not redirect to a page where you&#39;ll enter the passcode. In these cases, Amazon requires customers to log in on their device once and displays an error message saying that either the username and/or password is incorrect. Meanwhile, Amazon sends an OTP to the user&rsquo;s mobile phone number. Then, customers must sign in again, using their Amazon username, password, and OTP code.</p>

<h3>Netflix SMS Verification</h3>

<p>Netflix OTP verifications are one the most important constituents in the streaming service&#39;s security system. Users receive OTP code regarding any security-related activity, whether it&#39;s changing a password, payment method, or having a new user register.</p>

<p>Netflix recently applied a new security approach to solving password-sharing among users. When users select their profile on a shared Netflix account, a pop-up appears asking to verify the account by confirming with a text or email. If the account holder chooses to verify later, the pop-up shows up later at a random time. However, this feature is still in its testing phase.</p>
