I have a problem with users getting a call and when they answer there is no one on the other end. Sometimes it is someone calling in and somewhere along the way, the ccm fails to continue the call. However, I had a problem similar to this in the past, and the solution to this was to find phones that had been removed from the network but not from the ccm. Once I removed those, the phantom calls stopped. I do not have any extra phones on the network now and I am at a loss as to the cause. Anyone have any ideas?
