Please take a look at this document. It explains the conversion from SIP to SCCP and the reverse process.

Re: Removing SIP

No, the phone must load the files via tftp. If use ccme, it's just a matter of copying files to the router, configute tftp-server statements for all the files, configure load under telephony-service, configure an ephone with the mac-address.

Hope this helps, please rate post if it does!

Re: Removing SIP

Hi,

are you using an external TFTP server or the router ? If the latter, please check again cofiguration including mac-address, and do "term mon" and "debug tftp events". You will see the phone requesting files and which one is failing.

If that doesn't work we can use the method with the text configuration file, and binary utility. But first please confirm the above.

Re: Removing SIP

Yes you need the "config file and utility" method because your phone is a 7912.

You need to download the utility "bmp2logo.zip" from CCO, area "Cisco Unified IP Phone Client Tools ", note you need to be registered as customer with download privileges (requires a support contract aka smartnet).

You need that also because the V5.x firmware that you mentioned is too old for current CME, only the very latest image 8.0(3) is almost bug free.

Please read:

Prepare the config file just as mentioned in the thread. copy the binary file to router as gkdefault.cfg and configure with "tftp-server gkdefault.cfg. The phone will then upgrade.

I know it can look complicated but is the only way to do it. Good luck!
