7940G Convert SIP to SCCP

Last Modified: 2012-05-09
I received 12 7940G phones that were configured as SIP.  I need to convert SIP to SCCP to work on our CM7.4 in the Home Office.

Here's my lab setup (not connected to the Internet):
Cisco 1700 router ---> connected to 3560 switch (The router don't have CM configuration)
Desktop with SolarWinds TFTP Server ---> connected to 3560 switch
7940G phone ---> connected to the switch

The current version of the SIP firmware in the phone is P0S3-07-5-00.
I was able to download already SCCP firmware, cmterm-7940-7960-sccp.8-0-10.zip
The SCCP zip file is composed of P00308001000 .bin, .sbn, .sb2, .loads
I changed already the content of OS79XX.TXT to P00308001000
The following are in the root directory of my SolarWinds TFTP Server:

I managed to factory reset the phone and changed the IP on the same subnet as the desktop.  I also changed the TFTP setting of the phone to the IP address of the desktop which has my SolarWinds.

I tried to restart the phone and nothing happens.  I need guidance in making the SCCP upgrade succesful first on one phone, then to the remaining eleven.  Please help. Thank you.
