## Summary description

ALGO 8301 is a VoIP telephone adapter designed for SIP-based voice connectivity. It supports voice codecs G.711alaw, G.711ulaw and G.722 for clear audio, and uses HTTPS/TLS security for encrypted signalling. Powered via PoE, the compact unit (172×109×30 mm) is suitable for office or facility installations where secure, reliable IP telephony is required.

## Long description

The ALGO 8301 SIP Paging Adapter and Scheduler connects a VoIP telephone system to a traditional analog amplifier or public address (PA) system. The unit is powered via PoE (IEEE 802.3af) and includes wall-mount brackets for installation. It emulates a page port and functions as a SIP extension and multicast endpoint to deliver voice paging, loud ringing and emergency alerts through legacy amplifiers and connected speakers. The 8301 supports wideband G.722 and common narrowband codecs for improved speech intelligibility and provides isolated, balanced line output to prevent hum and noise.
Advantages
The 8301 offers a dry, configurable line output compatible with amplifier input impedances between 600 ohm and 10 kOhm, with both XLR and terminal block connection options and an optional dry contact closure to activate an amplifier. It supports multiple SIP registrations (including page, emergency alert and ring extensions), can initiate multicast streams to IP endpoints, and includes a scheduler with local storage for WAV/MP3 playback. The device supports secure SIP signaling (HTTPS/TLS) and PoE power, and is certified to relevant safety and EMC standards.
Suitable for
Integrating legacy analog PA systems with SIP-based VoIP telephony
School bell and scheduler systems (class changes, announcements)
Retail, healthcare and workplace public announcements and shift notifications
Emergency alerting and mass notification over analog speakers and IP endpoints
Hybrid deployments combining legacy amplifiers and multicast-capable IP speakers

How to use
Mount the ALGO 8301 using the supplied wall brackets and connect the device to your network with PoE or a PoE injector. Connect the isolated balanced line output to the input of a legacy amplifier (XLR or terminal block) and configure the output level to match the amplifier input impedance. Register the required SIP extensions for page, emergency alert or ring functions and upload any WAV/MP3 files for scheduled playback or alert tones. Optionally configure multicast targets to stream audio to IP speakers and other endpoints, and set up the embedded scheduler with NTP for timed announcements.
Usage recommendations
The 8301 is intended to drive a single amplifier; use one adapter per amplifier in multi-amplifier systems. For microphone connectivity, use the optional audio interface where required. Configure emergency alert extensions and Call To Cancel behavior during installation, and test multicast and analog outputs to verify simultaneous operation across legacy and IP devices.
