What the Snom PA1+ Actually Does
The Snom PA1+ is a SIP-to-analog paging adapter that registers as an extension on your VoIP system.
Once connected, you can dial your paging system just like calling another phone.
- Connect VoIP systems to analog paging systems
- Support multicast or direct paging
- Integrate with existing amplifiers or speakers
- Trigger external devices via relay outputs

Quick Setup: How VoIP Paging Works
Setting up the PA1+ is straightforward for most VoIP environments:
- Register: Add it to your phone system as a SIP device
- Connect: Wire it to your speakers or amplifier
- Page: Dial the extension to broadcast announcements
Once configured, paging works just like calling another phone.
Here’s a simple example of how the PA1+ connects to an existing amplifier and speaker system:
Typical setup: VoIP network → PA1+ → 3.5mm Audio Cable → Amplifier → Speakers. (Check your amplifier's input type before ordering cables!)
The Real Value: Modernize Without Replacing Everything
Replacing a full paging system with SIP speakers can cost thousands, but often isn’t necessary.
The PA1+ lets you reuse existing speakers and wiring while adding VoIP functionality, making it one of the most cost-effective upgrade paths available.
Best Use Cases for the Snom PA1+
1. Retrofitting Existing Paging Systems
If your building already has analog ceiling speakers installed, the PA1+ is often the fastest and most cost-effective way to bring paging into your VoIP system.
- Warehouses
- Schools
- Retail stores
- Office buildings with legacy paging
2. Small or Large Paging Setups
The PA1+ works for both small and large deployments.
For smaller areas, you can connect a speaker directly. For larger systems, it integrates with your existing amplifier to cover multiple zones or entire buildings.
3. Noisy Environments & Visual Alerts
In many environments, audio paging alone isn’t enough.
On factory floors, warehouses, or machine shops, announcements can easily be missed due to noise.
The PA1+ can trigger external devices such as strobe lights or visual ringers during a page, helping ensure alerts are noticed.
4. Access Control & Device Triggering
The PA1+ includes programmable relay outputs that can be triggered from a phone call.
- Unlock doors remotely
- Open gates or garage doors
- Trigger alarms or external systems
This makes it more than just a paging adapter. It can also act as a simple control interface.
What Changed from the Original PA1?
Some buyers remember limitations with the original PA1, especially around security and compatibility.
The PA1+ was designed to address those concerns.
- Updated hardware platform
- Support for modern VoIP security protocols (TLS, SRTP)
- Improved compatibility with current cloud and on-premise PBX systems
If you avoided the earlier model, the Plus version is a different experience.
Why IT Teams Choose the PA1+
Beyond basic paging, a few features can make deployment and long-term maintenance easier.
-
Gigabit Network Passthrough:
The PA1+ includes a Gigabit network port, allowing it to sit inline without slowing down connected devices. -
Centralized Provisioning (SRAPS):
For larger deployments, Snom’s provisioning platform allows devices to be configured and updated remotely, which can simplify management across multiple locations. -
Clean Integration with Analog Amplifiers:
The PA1+ is designed to connect properly with traditional paging amplifiers, helping avoid audio issues that can occur with mismatched signal levels. -
Longer Warranty Coverage:
Snom devices include a longer 3-year manufacturer advance replacement warranty, which can be beneficial for installations in hard-to-access areas.
Compatibility with VoIP Systems
The Snom PA1+ works with most SIP-based platforms, including:
- 3CX
- Asterisk
- RingCentral
- Zoom Phone

Power Supply (if no PoE):
👉 Snom Power Supply for PA1+
Required if you are not powering the device via PoE. The PA1+ uses a specific low-voltage power adapter, so it’s best to use the official Snom power supply rather than substituting with a generic adapter. -
Speakers (based on your environment):
• Horn Speakers (warehouses, outdoor, loud areas):

• Ceiling Speakers (offices, retail, schools):

• Wall Speakers (hallways, smaller rooms):

PoE Switch or Injector:
Using PoE (Power over Ethernet) simplifies installation by powering the PA1+ through the network cable. If you don’t already have a PoE switch, a PoE injector can be used instead. -
Audio Cables (for amplifier connections):
If you're tying into an existing amplifier, double-check your input type. Many setups require a 3.5mm to RCA or terminal block adapter, which is easy to overlook but essential for installation.

Frequently Asked Questions
Can the PA1+ work without an external amplifier?
Yes, for small setups, the PA1+ can power a single speaker directly. Larger installations typically require an external amplifier.
Does the PA1+ work with cloud phone systems?
Yes. It works with most SIP-based systems including 3CX, Asterisk, RingCentral, and Zoom Phone.
Do I need a power supply?
If you are not using PoE (Power over Ethernet), you will need a compatible power supply.
Can I use it to control doors or other devices?
Yes, the PA1+ includes relay outputs that can be used to trigger doors, gates, alarms, and other external systems.
Is the PA1+ still relevant compared to SIP speakers?
Yes, especially for retrofit projects where existing analog speakers are already installed. SIP speakers may be better for new, fully IP-based deployments.
