Audio to IP

Product: Audio Gateway (Or called as Audio to SIP converter too)

Audio Gateway, it is audio over Internet Protocol, or AoIP, that converts the sound from audio system (like: broadcast, mixer, microphone, speaker, etc) to VoIP SIP, as well as to PBX phone system.

Use Audio Gateway with an external speaker as a simple public address system, or with a microphone as a two-ways communicator on the principle of a simple IP intercom.


Audio interface from NICEUC Audio Gateway can be connected with mixer, microphone, loudspeaker box, conference system, broadcast, and so on, and then via Audio Gateway to make connection between these devices and SIP as well as PSTN.



Mass-market VoIP services started in 2004, and has been rapidly grew for recent years.

It is becoming increasingly common for telecommunications providers to use VoIP telephony over dedicated and public IP networks to connect switching centers and to interconnect with other telephony network providers.


In some islands, there is internal audio voice / broadcasting system only; in the field of dispatching system and emergency communication system, audio voice / broadcasting system is one of the commonest communication tool. With development of VoIP technologies, actually these audio voice / broadcasting system are isolated, and become the biggest obstacle for working performance. Therefore it’s imperative to integrate audio interface with traditional telephone communication network or with Next Generation Network (NGN) together.
