I have a strange happening. I have two registrations on my UCM6301 to one phone. I do have the “Concurrent Registrations” in the extension set up set to 3, but that is for Wave Desktop and Wave Phone. If I set the “Concurrent Registrations” to one, the phone is registered one time. If I set it back to “concurrent Registrations” to 3, the phone goes back to showing two registrations. Attached is a screenshot of extension 1104. Can you take a look?
