Snom has developed a SIP bridge (PA1+) enabling businesses to extend their existing public announcement speaker system while upgrading from digital/POTs systems into SIP-based voice communication solutions. The PA1+ can be used in both small and large applications due to the inclusion of a 6.5-Watt amplifier for single speaker projects. A microphone input is provided for two-way communication. Larger projects supported by 600ohm interface for better connectivity can utilize multiple speakers driven by external high wattage amplifier(s). The PA1+ serves as an auto SIP answering preamp that drives the multi-speaker setup. Use of Snom’s proven SIP stack enables wide compatibility with all SIP platforms.

Applications for the Snom PA1+ include:
1. Large PA systems driven by external amplifier(s).
2. Small PA systems driven by internal PA1+ amplifier (eg. door answering system), and internal relay to open door(s).
3. Phone ringer amplifier with ability to drive strobe light as visual indicator.
4. Multi-cast relay up to 4 SIP identities to four multi-cast IP addresses.
