Incorrect File Format error on call send, receive or end call
We have 50 yealink SIP-T32G phones here. Never any problems when manually configured.
The two most recent phones we had provisioned automatically through the boot server, something which we had not done in the past. The phones work for making and receiving calls, but both phones have a very strange error.

"Incorrect File Format" is displayed on screen every time a call is sent, received, or ended. It displays the error on the screen for a few seconds then disappears. The exact same error happens on both autoprovisioned phones.


Firmware Version
Hardware Version

Ive tried factory resetting the phone, and tried four different versions of firmware including the latest one. It is important I'm able to autoprovision these phones.
