The Snom PA1+ is a powerful SIP-based public announcement and paging system designed to expand your VoIP infrastructure with clear HD audio announcements and background music playback. Featuring an integrated 6.5 W Class D amplifier, it efficiently drives 8 Ω speakers or delivers high-level output (600 Ω) to larger PA systems, ideal for offices, corridors, and large rooms.

Equipped with Power over Ethernet (PoE IEEE 802.3af, class 3) and an optional external power supply, the PA1+ supports both IPv4 and IPv6 protocols and ensures secure VoIP communication via TLS/SIPS and SRTP/SRTCP encryption. The device includes a built-in Gigabit Ethernet switch with two RJ45 ports to connect additional network devices such as LAN cameras, facilitating expanded security setups.

Users can trigger announcements directly from any Snom SIP phone or multicast paging sources. The unit also supports freely configurable relay contacts controllable via SIP or DTMF, enabling integration with door systems and other external devices. For audio I/O, it provides two 3.5 mm jacks allowing headset connection for microphone and line output.

Provisioning and management are simplified with a menu-driven web interface and support for automatic provisioning methods including HTTP/HTTPS, TFTP, and secure Snom SRAPS. Diagnostic tools like SIP and PCAP traces are included to aid maintenance. The PA1+ can be easily wall-mounted using the provided mounting plate and screws.
