Moving 7942 from SCCP+CUCM to 3rd party SIP Server
I have a 3rd party SIP Server that I need to move a 7942 phone to. The phone is currently registered with CUCM 8.6 and the phone is configured with SCCP firmware. Here are the questions I need help with:
1. Do I have to do a factory reset to get the SIP FW on the phone currently running SCCP? Some of what I've read seems to say that you can do it without doing a factory reset but my tests haven't worked (changing the phone to SIP and specifying the load name).
2. If I change the phone to SIP FW using CUCM, should it be as simple as changing the TFTP Server? In my tests, after getting the SIP FW on the phone, it fails to register with the 3rd party SIP server. It's complaining about CTL and looking for SGN files so I cleared the phones "Trust List" but it still isn't working. Or, do I need another "Hard Reset"?
