Replacing SCCP to SIP on Cisco IP 7960

I got time (and enough motivation) to finally got rid of the SCCP firmware inside this Cisco IP 7960 that has been idle for years.


1. Setup a TFTP server
2. Put these files on the TFTP server
OS79XX.TXT
*.bin
(E.g., for v6.3, the file is P0S3-06-3-00.bin)
3. Set 7960 for firmware update
Press **# at the main window of 7960 to unlock the phone, then set DHCP to yes, and alternate to TFTP to yes. Then, press "*","6",Setting buttons at the same time to reboot. The 7960 will then boot with SIP firmware
4. Put these files on the TFTP server
OS79XX.TXT
SIPDefault.cnf
dialplan.xml
RINGLIST.DAT
5. Set the 7960 for SIP setting
Press "*","6",Setting buttons at the same time to reboot again. The 7960 will then booth with SIP settings according to the contents of SIPDefault.cnf and SIP<MAC addresss>.cnf (for example, SIP000B46CABF9F.cnf if the MAC address of the 7960 is 000B46CABF9F)
