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 4-watt amplifier for single speaker projects. A microphone input is provided for two-way communication. Larger projects 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.
Applications for the Snom PA1 include:
- Large PA systems driven by external amplifier(s).
- Small PA systems driven by internal PA1 amplifier (eg. door answering system), and internal relay to open door(s).
- Phone ringer amplifier with ability to drive strobe light as visual indicator.
- Multi-cast relay up to 4 SIP identities to four multi-cast IP addresses.
