Audio Gateway

Serial NC-MG320A Audio Gateway can interconnect with IP PBX, dispatching system or Soft Switch System by SIP protocol, as well as with operator by PSTN interface. Audio interface can connect mixer, microphone, loudspeaker box, conference system, broadcast, and so on, and make these device connect with SIP and PSTN. At present, it’s very difficult for many audio devices to connect with PSTN and SIP. In the field of emergency dispatch as well as in others, isolated island without any information is the biggest obstacle for working performance, therefore it’s imperative to integrated audio interface with traditional telephone communication network and Next Generation Network (NGN) together. New type of Audio Gateway from NICEUC is designed for such a requirement that can support 4-8 audio interfaces at the same time.
