The problem is with one particular 7960 IP phone. The phone reboots a few seconds into a conversation, but it only does it when it's called from certain callers everytime. Some of the calls are from the PSTN and some are local extensions within the same system. All other calls work fine. Has anyone else ever seen this?
Hi Mary Beth ... Thanks for the excellent information.What a strange trouble and one that would be nearly impossible to troubleshoot. It reminds me of a problem I once had on an Octel voicemail system where certain female voices would activate the "dial 0" funtion by approximating the DTMF tone of pressing the 0 key.
I checked the app logs and the phone just shows that it unregistered with CM whenever it reboots. There aren't any other errors showing up in the logs concerning the phone. The problem isn't with the volume either. I've used the phone in various locations on our campus with different DNs assigned to it and for the most part it works fine, but when certain callers call the phone, it just reboots without warning. Some of the problem calls are internal and some are from off-campus, but certain calls from the same callers always result in the phone rebooting.
Sorry for the long delay in getting back, I've been tied up with many other projects for a few days.

The short answer is that you don't.... That isn't entirely true while at
the same time it kind of is, but for the most part you don't configure
the softkeys. You enable or disable them via TCL. Here is the long
