The Astcode Signaling Gateway uniquely combines a SIP proxy server with SS7/C7 signaling intelligence to create the most cost-effective bridge between emerging VoIP networks and the PSTN. An integral part of sentitO's ONX architecture, the Astcode works in conjunction with the IVG and third-party feature servers to help global service providers reduce the costs and complexities of integrating VoIP and legacy signaling networks.

 

The Astcode combines proxy, redirect, registrar, and authentication functions to ensure carrier-grade performance and reliability of SIP endpoints and to cost-effectively terminate SIP-based voice traffic onto the PSTN. The Astcode uniquely allows service providers to deliver VoIP services to traditional POTS customers by allowing third-party VoIP feature servers to "dip" existing SS7/C7 databases and features. For the first time, service providers can make a seamless transition to VoIP services, ensuring that no customer gets left behind.

The Astcode packages and translates ISUP messages into SIP to eliminate signaling backhaul requirements for carriers using SS7 IMT trunks. This greatly reduces the costs and complexities of signaling across international networks, as all traffic is transported over managed SIP networks and then converted locally to the appropriate SS7/C7 signaling variant.

The Astcode scales to well over 100,000 BHCC and natively supports over 40 international signaling variants to ensure carrier-grade deployment of VoIP services around the world. With broad-based routing capabilities, including E.164, CICs, Time of Day and SIP addresses, the Astcode simplifies the deployment of VoIP services and transport, while preparing carriers for the expansion of their VoIP service offerings.
