How to change the firmware from SIP to SCCP on 7960

Unanswered Question
Feb 25th, 2007


I have 4 Cisco 7960 Phones with SIP Firmware. Can anyone please give me some instructions to replace the SIP firmware to SCCP? I would like to use these phones with Call Manager Express. I tried factory restore but no luck.



I have this problem too.

Applied to CME, the procedure consists in:

1) copy files from zipfile to router, you can use a directory if supported by the platform.

2) for each file, configure tftp-server, with alias as needed.

3) configure ephones with the corresponding mac address and type.

4) configure load under telephony-service for each phone type.

5) connect the phones to network.

Debug tftp events is the main troubleshooting tool for the above.
