Coverting a Cisco 7940 SIP to SCCP

I had worked on this for almost two days and finally managed to figure it out… lots of people are having issues converting Cisco 7940 from SIP to SCCP…

Make sure that you have the following files in your TFTP server:

– SIPdefault.cnf: change the first line, which is image_version: “P00307000200”, you might have something like “P003-08-8-00” which is a SIP firmware

– SEP.cnf.xml this file is very important and you must have the following in the file:


and you need the firmware files .bin, .loads, .sb2 and .sbn

Once you reboot the phone, the phone will download SCCP firmware.
