Yealink T26 CTI Not working

[Philip Darnell]

Hi

I've just setup a 3CX system for a small customer with 4 Yealink T26 phones on a remote site using an SBC, when trying to use the 3CX Phone manager in CTI mode it just doesn't do anything.

The T26 is an End-of-Life model and I do not believe has the updated CSTA code to support this functionality.

Hello @Philip Darnell

As mentioned these phones do not support uaCSTA as they are End-Of-Life models. A full list with their limitations can be found here: https://www.3cx.com/sip-phones/yealink-t20p-t22p-t26p-t28p/#h.e2e9dlym4hi8
