The right model depends on the existing paging equipment, required connections, speaker-zone configuration, and broader deployment requirements. The sections below compare the available options and explain where each model fits.
What Do Algo IP Paging Adapters Have in Common?
All four models provide core capabilities for connecting existing paging infrastructure to SIP-based communication platforms:
- PoE: IEEE 802.3af Class 0, 48V, 15.4W

- Zero-touch provisioning
- Supervision: Algo Device Management Platform (ADMP), Algo 8300 IP Controller, any third-party SNMP monitoring software, and RTCP
Which Algo IP Paging Adapter Should You Choose?
While they all share a similar foundation, each paging adapter has key distinctions suited for different use cases.

| Model | Best For | Key Distinction |
|---|---|---|
| 8301 IP Paging Adapter & Scheduler | Organizations looking to connect existing analog paging systems to SIP platforms. | Connects to an analog paging amplifier and includes one Smart Relay Input. |
| 8305 Multi-Interface IP Paging Adapter | When working to integrate legacy communication systems—specifically ones that have FXS and need to connect to a telephone/FXO port—to an IP based system. | Includes a Phone Port and Terminal block 8 Ω Out. |
| 8312 Expanded IP Paging Adapter | Organizations that need base-station-free handheld radio integration, more I/O, and expanded communication options. | Includes Radio, 12 Sensor Inputs, independent paging and radio audio volume control, and USB-A. |
| 8373 IP Zone Paging Adapter | When working to integrate legacy analog infrastructure and amplified signals which require three or more physically wired zones, adapting the amplified audio across 3 shielded speaker outputs. | Supports multiple analog speaker zones using three shielded speaker outputs. |
Algo IP Paging Adapter Feature Comparison
| Feature | 8301 | 8305 | 8312 | 8373 |
|---|---|---|---|---|
| Scheduler | Yes | Yes | Yes | No |
| Microphone connection | Yes | No | Yes | No |
| FXO port | No | Yes | No | No |
| Multiple analog speaker zones | No | No | No | Yes |
| Page SIP extensions | 50 | 50 | 50 | 50 |
| Emergency Alert SIP extensions | 10 | 10 | 10 | — |
| Ring SIP extensions | 10 | 10 | 10 | — |
The 8301, 8305, and 8312 support only DTMF-based multicast zone selection. The 8373 supports multiple analog speaker zones.
How Is the 8312 Different From the 8301?
The 8301 is best for organizations looking to connect existing analog paging systems to SIP platforms. The 8312 is optimized to integrate with base station-free handheld radio systems, such as Motorola Curve, and adds more inputs, independent audio control, and a USB expansion port.

8301 IP Paging Adapter
The 8301 is the ideal paging adapter for most applications. The 8301 is the most direct paging gateway for bridging VoIP and analog systems. It’s designed to be a balanced line output to a single amplifier.
If you have multiple amplifiers in a facility, they would all require an 8301. After you SIP register this device and connect it to your legacy system via the balanced line input, you can call the device to drive your speakers. You can configure the device via a web interface for your paging and multicast needs.
The 8301 also supports a microphone connection and talkback when an appropriate speaker and microphone are connected.
8305 Multi-Interface IP Paging Adapter
The 8305 is the ideal paging adapter for integrating legacy communication systems that provide a talk battery or trunk port (functionally similar to an FXS line). It is very similar to the 8301, however, it was explicitly designed to create a hybrid VoIP environment by emulating an analog telephone and initiating a page through an off-hook action.
The 8305 has three key connection points: a telephone port that emulates an analog telephone line, an 8 Ω output that connects to self-amplified speakers, and a line output. As a SIP-compliant device, the 8305 makes it possible to connect existing legacy paging systems to VoIP or UCaaS platforms. The 8305 is also multicast-capable, enabling legacy systems to be used alongside IP devices.
8312 Expanded IP Paging Adapter
The 8312 is the ideal paging adapter to bridge UC platforms, legacy paging systems, compatible base station-free handheld radio systems, and automated communication workflows into a single IP-based communication.
It is very similar to the 8301, however, it adds handheld radio system integration, 12 sensor inputs, independent paging and radio audio volume control, and USB-A.
8373 IP Zone Paging Adapter
The 8373 IP Zone Paging Adapter is the ideal paging adapter for supporting multiple analog speaker zones and adapting amplified audio across three shielded speaker outputs.
This IP paging adapter is best if you want to retain zoning speakers as-is. The 8373 contains three high-powered relays that can be used to switch a single amplifier’s output signal.
Analog speakers must be appropriately wired to the 8373 internal relays, which can switch up to 280 W using a 70 V amplifier or 400 W using a 100 V amplifier.
