When someone stands at a door or barrier, you want to be able to communicate with the visitors remotely before letting them pass. With the Robin SIP audio intercoms, a voice link is established with a preconfigured extension or group number the instant someone presses the bell. Conversely, a direct link can also be made from the PABX to the intercom. The Robin intercom systems are connected by means of the SIP protocol to a large variety of PABX and telephone systems. You can find a compatibility overview at product level.
