Algo 8301 PoE IP Voice Paging Adapter | Audio Streaming and Bell Scheduler Pre owned/ good condition/ item pictured is the exact item you will receive The Algo 8301 is a PoE-powered IP voice paging adapter and bell scheduler that bridges a VoIP/SIP network to a legacy analog PA amplifier, while also handling scheduled tones, bells, and announcements. It supports wideband audio streaming, SIP extensions, and an internal scheduler for automated audio files or tones to play over speakers at set times.? What it does The 8301 presents itself as a SIP endpoint on your IP/VoIP system and outputs a balanced, isolated line-level signal to a traditional analog amplifier for paging, loud ringing, and emergency alerts. It also includes a contact-closure input and music/aux input so it can insert IP audio or emergency messages over existing audio sources when required.? Audio streaming and codecs The unit supports wideband G.722 HD voice as well as standard G.711 for higher-intelligibility speech paging and emergency notifications. It can receive a SIP call and play live audio, or multicast audio streams (including stored WAV files) to other Algo IP speakers, adapters, and endpoints on the network.?? Bell and tone scheduling The built-in scheduler uses NTP time to trigger playback of stored WAV files (bells, tones, announcements) at specific times and days, allowing multiple schedules for different zones or events without a PC running. Schedules are configured via a web interface, and different SIP extensions can be mapped to different alert or ring tones stored in the device?s internal memory.?? SIP, zones, and integration The 8301 is a 3rd?party SIP-compliant endpoint compatible with most hosted/cloud and on?prem VoIP systems, including support for multiple SIP registrations such as page, ring, and emergency alert extensions. It is typically used one per amplifier (single zone per unit), while multicast lets you fan out audio to multiple Algo devices to build multi-zone paging and all-call groups.?? Power and installation basics The device is powered by standard PoE (IEEE 802.3af), avoiding a separate power brick and simplifying wiring to the network switch. It is usually wall-mounted near the legacy amplifier, using the balanced/isolated line output to minimize hum and noise when feeding the amp?s line input. We are wholesaler/liquidators.
