IP Phones Designed for FreePBX

Sangoma S-Series IP phones are the only IP phones on the market specifically designed to work with FreePBX phone systems. 

Featuring ZeroTouch auto provisioning, S-Series phones can be quickly and easily used right out of the box. All you need to do is plug them into an Internet connection, wherever you are in the world, and the redirection service will automatically pair and configure the phone with the phone system. This makes life easier for IT administrators and allows end users to setup their own phones within seconds, including remote users. 

Also, when you pair S-Series phones with FreePBX, the EndPoint Manager module is automatically activated, for the life of your phone system.

Value-Based Phones

Sangoma’s value-based P-Phones deliver the essential features you need at the best price point. Perfect for manufacturing, education, and retail environments, these IP phones feature auto-provisioning across Sangoma’s product portfolio, including Switchvox, PBXact, FreePBX, and Asterisk.

S-Series Benefits


Zero-Touch Auto Provisioning

S-Series phones automatically provision using Sangoma’s redirection cloud server, which authenticates S-Series phones and redirects them to the PBXact/FreePBX phone system.



Each S-Series phone is factory imaged with a unique serial key. This prevents hackers from contacting the redirection server, pretending to be an S-Series phone, and trying to register with the MAC address.


Programmable Buttons

Customize your phone with the applications you need where you want them. This allows users to improve efficiency and, ultimately, their productivity.


For realtors, secretaries, and receptionists, the EXP100 sidecar adds extra BLF (Busy Lamp Field) buttons to S-Series IP phones for extra functionality.

Power over Ethernet

Power S-Series phones directly from the Internet cable connection, rather than trying to search for a wall socket for power. This allows you the freedom to place your phones wherever you want.


S-Series phones support TLS/SRTP encryption, so hackers cannot try and intercept the call path or listen in to the call.


Advanced Phone Applications

S-Series phones feature PhoneApps, which are on-board applications controlled on the phone display without the need to dial in feature codes.  


Built-In VPN

Connect to the corporate phone system from remote locations securely with built-in VPN.

What makes Sangoma PhoneApps so different from other PBX vendors?

Open-Vendor Support

PhoneApps are the only software suite on the market that integrates advanced features, not only for Sangoma IP phones, but for many third-party manufacturers. Some vendors offer their own version of our PhoneApps, but they are only compatible with their own PBX and IP phones. This locks you down or forces you to buy new hardware.

Server Side

PhoneApps are installed on IP Phones, but completely controlled by the PBX (PBXact or FreePBX). This keeps the intelligence of each PhoneApp with the PBX, something very unique that other vendors don’t do. Think of PhoneApps as a web client that resides on the IP phone, with the PBX acting as the web server. The user navigates the phone display to use the PhoneApps, but the changes are actually occurring at the PBX.

For example, the Do Not Disturb app enables the DND status condition for that user directly on the PBX. So even if the phone loses network connectivity, the status condition remains in place on the PBX.
