The Cisco Multiservice IP-to-IP Gateway facilitates easy and cost-effective connectivity between independent voice-over-IP (VoIP) and Video networks. It provides a network-to-network interface (demarcation) point for billing, security, call admission control, quality of service, and signaling interworking.
The Cisco Multiservice IP-to-IP Gateway will perform most of the functions of a PSTN-to-IP gateway but will join two H.323 VoIP call legs. The voice quality is preserved because media packets flow through the IP-to-IP gateway without any encoding or decoding.
