Okay I give up and need help. I can't get the phone to download the SCCP code from my TFTP server. I edited the OS79XX.TXT file and have only the line P0020301.

I tried to find the UNSIP.ZIP file on CCO without luck.
What do I have to do to kill this !@#$ SIP protocol?

Update your OS79xx.txt to reflect the new load and you should be set.
