We've used overlay in the past, but does overlay of a single extension have a liiotation? i.e. you can only get one overlay per extension?
We had a 7921 that was overlayed with X 201, the 7921 was physically removed from the UC, not logically or programatically remoevd, but is now back at a different extension. I assume a new ephone config as well becuase we had to manually add it to CCA for it to register with CME.
I think that the phone at extension 201, has a "hidden" overlay on another phone, how can I see this in the config? We are trying to overlay X 201 but get errors in the Unity Express GUI and CCA does not offer X 201 as a choice.
