Description
Versions:
- Algo 8312 (SIP)
- Algo 8312-IC (InformaCast)
The Algo 8312 Expanded IP Paging Adapter gives facilities managers, IT directors, and business owners a single PoE device that unifies SIP-based UC paging, legacy analog amplifiers, and compatible base-station-free handheld radios. It builds directly on the proven 8301 foundation and adds radio integration, twelve extra sensor inputs, independent paging and radio volume controls, plus a USB-A port. Critical messages now reach desk phones, overhead speakers, and radio users at the same time without separate systems or custom wiring.
**Please note you may need the 79-00062 Radio Connector Cable for this product.
The Telecom Spot Take
This adapter is ideal for organizations that already run or plan to add base-station-free radios (such as Motorola Curve) alongside VoIP or UCaaS platforms. The extra sensor inputs and independent audio paths let teams trigger automated announcements from buttons, door contacts, or equipment sensors while keeping radio and paging levels separate. It simplifies hybrid environments where staff move between offices, warehouses, loading docks, and outdoor areas. Businesses that need reliable, network-managed bridging without replacing existing amplifiers or radio fleets will find the 8312 a practical, single-device solution.
Key Features
- Bridges SIP UC platforms to legacy amplifiers and compatible base-station-free handheld radios so announcements reach phones, speakers, and radios simultaneously.
- Twelve additional sensor inputs (normally open or closed) plus one smart relay input support event-driven triggers from buttons, sensors, or equipment.
- Independent volume controls for paging and radio audio paths keep levels optimized for each audience.
- Built-in scheduler stores up to 1 GB of WAV or MP3 files for automated bells, tones, and announcements synchronized via NTP.
- 50 page, 10 emergency alert, and 10 ring SIP extensions with multicast support for scalable zone coverage.
- Balanced and isolated line-level outputs (terminal block and 3.5 mm) connect cleanly to existing amplifiers without hum.
- PoE powered, web-configurable, and compatible with major UC platforms including Microsoft Teams.

Comparison at a Glance
- Versus Algo 8301: The 8312 adds base-station-free radio integration (e.g., Motorola Curve via RJ12), 12 sensor inputs, independent paging/radio volume, and USB-A while keeping the same scheduler, SIP extensions, and amplifier connectivity.
- Versus Algo 8305: The 8312 focuses on radio + sensor expansion rather than FXO/telephone-port emulation.
- Versus Algo 8373: The 8312 is optimized for radio bridging and sensor-triggered workflows; the 8373 is built for multi-zone analog speaker control.
FAQ
What radios work with the 8312?
It is optimized for base-station-free systems such as Motorola Curve using a donor radio and the optional 79-00062 Radio Connector Cable. Contact Algo for other radio compatibility. For systems that use a base station, the 8301 is often preferred.
Can it send the same page to both speakers and radios?
Yes. Audio output is selectable as Page Only, Radio Only, or Both so announcements reach overhead systems and handheld radios at the same time.
How many sensors can trigger actions?
Twelve dedicated sensor inputs plus one supervised smart relay input support normally-open or normally-closed dry contacts for buttons, door contacts, motion sensors, or equipment alarms.
Does it replace my existing amplifier?
No. It provides a balanced, isolated line-level output that connects to most traditional amplifiers so you keep your current speakers and cabling.
Is it compatible with Microsoft Teams?
Yes. It registers as a third-party SIP endpoint and is listed among Algo devices compatible with the Teams SIP Gateway.
How is it powered and managed?
It is fully PoE (IEEE 802.3af). Configuration is done through a browser-based web interface or central provisioning. It is supervised by the Algo Device Management Platform (ADMP) or third-party SNMP tools.
