Hi! I have three Cisco phones for my tests, a 7960, 7965, and 7975. The 7965 is OK, but the 7960 and the 7975 can't register.
Is there something special that needs to be done for these phones to register?
When doing a WireShark trace, I noticed that the configuration has "USECALLMANAGER" for some of its values, and the phone seems to be using that literally.

If I manually set some of the information, then the phone can work.
Where do I set this information in the server?
