The Clarent\u00ae<\/span> Class 4 Call Manager<\/strong> (C4CM) is the strategically crucial central call control element of IPVision’s end-to-end PSTN access softswitch solution. This Class 4 Call Manager cost-effectively performs the key functions of call routing, user authentication, connection control, internet offload, and signaling of the Clarent\u00ae<\/span> BHG<\/strong>. (Connection control refers to the setup and teardown of calls).
\nUser authentication is specific to the processing of transactions after the Clarent\u00ae<\/span> Command Center clears user authentication and establishes the account to be charged.
\nThe interface between the Clarent\u00ae<\/span> C4CM<\/strong> and gateway includes TPNCP and MGCP. This suite of protocols subsequently accommodates the full spectrum of service providers communications needs. Adopting these open protocols assures that the Clarent\u00ae<\/span> C4CM<\/strong> will be a smooth integration for IPVision\u2019s customers across the globe, with an inherent scalability that takes traditional circuit switching to the next level of telephony evolution.
\nThe Class 4 Call Manager (C4CM) is carrier-grade, UNIX based, NEBS-compliant. As the central call control element in IPVision’s PSTN Access Softswitch solution, the C4CM is designed to augment or replace Class 4 telephony switches.<\/p>\n<\/div>\n<\/div><\/div>
