IP-A1PG IP Paging Gateway

IP-A1PG

The IP-A1PG is a PoE-powered Gateway Unit that integrates multiple IP Audio devices by converting the SIP voice or ONVIF Backchannel audio into multicast audio streaming. It can also transmit built-in sound source or input audio as multicast audio streaming. Moreoverm the event broadcasting triggered by control input, scheduler or remote API (HTTP) as well as the command set that sends multiple HTTP commands simultaneously are also available.
