Business

The broadband VoIP (Voice over IP Packet) media gateway, is a key element of a packet-based Next Generation Network (NGN). As a high-density carrier grade gateway, it can offer up to 10,000 DS0 channels and E1/T1 N+1 redundancy and STM-1 1+1 redundancy, while supporting a variety of voice codecs and high-quality VoIP service. Built for the networks of major telecommunication operators, it provides a stable communications network and high-quality service, reducing operator CAPEX/OPEX.
