[cisco-voip] Cisco 7912 phone registration issue

[Nate VanMaren]

Faye,

I feel reluctant to share this, because it took me so very much time to figure it out.  TAC was not very helpful, and there are some guides on the internet that are not very good.

But since I am a really nice guy and hopefully it will be paid forward:

The best #1 way to fix this!  (assuming you have auto-registration enabled)
In you device defaults for the SIP 7912 change it to the same exact firmware that you have as the default for your SCCP 7912.  If you're like normal people you'll never want a SIP 7912 to this will not be a problem.

Then delete all of the SIP 7912 devices, and keep deleting them until they don't pop up.

Thanks
-Nate

Subject: [cisco-voip] Cisco 7912 phone registration issue

We are running CM 7.1.5 (recently upgraded from 7.1.2). We've always used SCCP. I have 22 of the Cisco 7912 one-line phones currently registered in my system that were legacy items when we did the upgrade. Today, I tried to add a new/off-the-shelf/never been plugged in since purchased in 2008 7912 to my call manager but it won't register. Additionally, the phone display shows auto-reg (which we've never used) in the upper right corner, and the network configuration info on the phone shows odd items - host name with gk in front of it, time zone 20 or 17 (varies on reboot).
The SIP configuration item is fully populated with proxy, user id auto-reg, password, SIP port number, register with proxy: Yes, etc.

I've tried erasing the config, factory reset, and every tip I can find anywhere but it still won't lose the SIP info and register with Call Manager. Can anyone give me some ideas of what to do with this phone (other than trash it), please?

Thanks,


Faye Day
