Integrating Yeastar S-Series VOIP PBX with Snom PA1

Snom PA1 unites the functions of a telephone with a high-performance digital amplifier for broadcasting announcements and supplying background music to assigned rooms, hallways, and office floors. This article provides configuration instructions on how to connect Snom PA1 to Yeastar S-Series VoIP PBX.

Like SIP phones, Snom PA1 can register extensions provided by IP PBX. For example, Snom PA1 registers the extension 1000 of PBX; once registered, other PBX users could dial the extension number 1000 to make a broadcast. To be more specific, when a user dials the extension 1000 and his/her IP phone status shows connected, then he could make an announcement over the handset and Snom PA1 would broadcast the announcement with loud-speaker or handset connected to it.
