I am using the latest master from fusion PBX. I have a client that has 17 YeaLink T 54W and they connect via UDP no issue. The YeaLink W 60 B will only connect with the hands sets on TCP but not UDP. Registration fails on UDP but not TCP. I would like to keep everything on UDP. I have disabled only except trust certificates on the Link W 60 B. I have looked at logs and I just can’t seem to find out why registration fails on the yealink W 60 B on UDP but all the year Link T 54W will register successfully on UDP.
