Supported phones


You don't have to purchase all of your components for your telephone infrastructure from the same vendor. Interoperability has come a long way, but today you have a great choice on all sorts of devices that work well together. This page shows you which devices have been integrated with the PBX.

FXO/FXS Gateways


1 Provisioning means the phone will receive all its settings, like registration infomation, buttons if available and other settings from the PBX. The phone has to be directed towards the PBX for provisioning.
2 LAN provisioning means that the PBX detects a phone that is plugged into the LAN and lists it in the web interface, so that the administrator can assign it to a domain and extension.
3 Zero-touch requires that you have an account with the vendor for redirecting calls from their redirection service.
4 Encryption means that the phones are using TLS and SRTP to the PBX. Call recording and other features like call barge in on the PBX will work. Other encryption mechanisms like ZRTP may also be available. Please note that for Yealink, Grandstream and Cisco SPA, encryption is not on through provisioning, although you may do it manually.
5 Buttons means provisioning of the phone buttons (like BLF etc.) when available. Some phone models may have changed the way their buttons function in new versions and may not be compatible but we generally try to adapt to keep them compatible.
