Hello everyone, I hope you are doing well.
I have a problem and I still haven’t found a solution.
When I make a call to another extension from the Yealink T21PE2 telephone and the call is rejected or even if the other point is busy, I have the following value “0,850;cause=17” returned on the telephone screen.
I’ve already commented out some dialplan lines, but I haven’t heard any results. Could someone help me?
