Recently I had to delete an extension and rebuild it because the former employee’s voice messages wouldn’t go away. We recorded new ones for the new employee but they just wouldn’t “take.” I made sure (I think) to make sure all settings were the same as the previous settings on the extension, and I added the extension back to the various outbound routes’ permission lists. The extension can call out on the first outbound route, which is an analog line. If that line is in use, all phones call out over the SIP trunk provisioned to the UCM6102. The firmware on this device is pretty old - 18.104.22.168. I have plans to bring it up to the final version of firmware for the 6102, but haven’t done it yet.
The phone displays error q.850;cause=19. No other extensions are experiencing this issue.
The phone is a Yealink T46S. This is one of the older installs that I have out there - about three years ago before I moved to Grandstream phones.
An ideas the gurus here may have would be much appreciated!
