• Provides advanced telephony features such as long-haul, pulse metering and country-dependent MWI and CID, enabling integration with existing telephony features

• Dynamic bandwidth allocation using Voice Activity Detection and silence suppression, leaving more bandwidth for data transport

• Fully interoperable with leading softswitches and SIP servers, simplifying system integration

The Vmux-310 VoIP SIP analog gateway is an analog VoIP gateway designed for commercial VoIP deployment. It provides superior voice technology for connecting legacy telephones (POTS), fax machines and PBX systems over IP-based telephony networks, as well as for integration with new IP-based PBX architectures.

Using standard G.729A, G.726 and G.723.1 compression algorithms with Voice Activity Detection and silence suppression, Vmux-310 VoIP SIP analog gateway provides efficient bandwidth optimization, leaving more bandwidth for data transport. It optimizes voice transmission for satellite links, pay phone networks, and centralized IVR and Quality Monitoring applications. The unit can also be deployed in MTU (Multi-Tenant Units) broadband access networks, IP Centrex and rural applications.

In addition, the product provides advanced telephony features such as long-haul, pulse metering and country-dependent MWI and CID, for true integration with existing telephony infrastructures. The Vmux-310 was designed and tested to be fully interoperable with leading soft switches and SIP servers.
