Does anyone know how to reset to factory defaults a 7906? I've been no lucky in my search through the web :(
I've got a 7906 that was registered to a CUCME 4.0 A, and it has been moved to another CUCME 4.0 B.
Now it gets the IP@ and the TFTP@ from the new CME B but it still has in its configuration the IP@ of the old CME A.
I don't know why it is not refreshing that info as it has connectivity to the new CME B and there is another 7906 registered to this new CME B. In fact, my 'faulty' IP Phone was also previously registered to this CME B (some days ago).
So the only thing I can think about is resetting to factory defaults the IP Phone to see if it gets the right info.
Follow the steps in the following link to erase the local configuration.
Hope this helps. If so, please rate the post.
