We have all 796x serier SCCP phones registered with CUCM 6.1.4. From time to time we need to reboot a phone in order to add an extension to the phone. How can I tell if the phone is in use?
On a gateway router I can do "sh voice call active summary" to get an off/on hook status. There must be some way to do that with CUCM.
Simply calling the phone doesn't verify anything since the person could be in a conference and simply not answering the call.
Just add it.
If it's in use, nothing will happen until the person hangs up the phone, then the change will apply.
