Service Provider VoIP Gateways

IMG 1010 Media Gateways

The Sangoma IMG 1010 Integrated Media Gateway is a carrier-grade VoIP gateway that supports both media and signaling in a single chassis. It allows service providers to add new telephony services quickly and gives them a clear migration path to an all-IP network.

It provides any-to-any voice network connectivity and can deliver SIP services into legacy PRI, CAS, and SS7 networks, as well as IP-to-IP transcoding and multimedia border element functions, such as SIP mediation for network edge applications. Its compact 1U high-density design, integrated SS7 termination across multiple gateways, GUI-based management, and software licensing for in-service capacity expansion make the Sangoma IMG 1010 an excellent option for VoIP.

The IMG 1010 media VoIP gateway is available in:

  • 768 TDM channels per 1U shelf (scalable from 3 E1/ 4 T1 to 24 E1 / 32 T1) 96 - 1024 VoIP channels per 1U shelf
