• Flexible and efficient VoIP Gateway Solution

With its scalable density and versatility, SMG2000 can help enable wireless and wireline service providers to add new Value Added Services (VAS) quickly, and provide a clear migration path to an all-IP network. It can scale up to 120 simultaneous IP sessions and at the same time provide media transcoding and impressive sessions per second. 

SMG2000 support voice densities ranging from 30 to 120 channels, call routing, call translation and IP transcoding in a single mini chassis for gateway operations. The integrated gateway functionality not only provides interworking between IP and TDM domains, but also automated failover from IP to TDM for outbound routing. These features help service providers looking to improve network and routing resiliency and lower TCO. These capabilities make the CMG2000 an excellent option for mobile VAS, SIP trunking, contact center and emergency service deployments, as well as for retail, wholesale, business, and enhanced Voice over IP (VoIP) services.

• Any-to-Any Signaling and Multimedia Connectivity

SMG2000 provides any-to-any network connectivity through its ability to interwork multiple protocols used by telecommunications providers to deliver services to their retail, business and wholesale customers. It can provide interworking between ISDN, SS7, SIP formats.

SMG2000 also supports any-to-any media transcoding for popular voice codecs. T.38 and G.711 fax interworking and support for RTP, INBAND and SIPINFO method based tones and event handling complement the media transcoding capabilities to provide a high degree of flexibility to help deliver value added services economically.

• User-friendly management and configuration toolkits

The Web graphical user interface (WebUI) is a real-time web toolkit to configure, monitor CMG2000. It allows operators to configure and perform real-time monitoring and maintenance. Flexible SIP and Protocols configuration enable services providers and enterprises to seamlessly connect in hybrid networks, Helping configure SIP, SIP trunking, SIP Mediation, PCM, SS7and ISDN, Routing and more; And a broad range of gateway toolkits also help gateway’s maintenance and software upgrading for Web UI, gateway services and firmware.
