Yealink 32G Issue with 3CX Build 15.5.13103.5

[David Blumberg]

We have around 80 yealink desk phones and when a user tries to call an internal user using the web client the browser indicated "no phone is connected" even though the desk phone is working. We have reset the phone, regenerated credentials, etc.. and this is across the board on the yealink 32g phones. The 3CX server has been updated to the newest build as well as all phone configs. All other yealink phones work fine, is this a bug in the config file for the 32G?

These phones are classified as legacy and do not support all the functions within 15.5 These phones do not support CTI via uaCSTA - check out limitations

This is how ver 15.5 communicates with the phones.

So are you saying that this update made these phones obsolete?

What version did you upgrade from ?

They are not obsolete, still works as a desktop - just does not have the full functions

Hello @David Blumberg

Please note that since these phones have reached their End of life, Yealink no longer provides new firmware for these phones so they can support the latest functionality. The web client uses uaCSTA that these phones do not support. You can still use the windows client to control these devices though.
