I am trying to get two 7940 phones back to SCCP. I found this article but something is missing
I have CME 4.1 running on my router and the firmware for both SCCP and SIP installed. The phones have P0S3 -05-02-00 installed on them and I followed the instructions about changing the name in the OS79XX file. According o CISCO the boot process would look at the first 4 letters in the file and if they do not match It will pull the new files. This is not working as stated by cisco.
Is there something different I need to do in the router? Set up the telephony service loads differently?
