I have downloaded this file cmterm-7940-7960-sccp.8-1-2.cop.sgn
I wander how I can use it...it didn't open by ZIP/RAR...
Please notice that only this file cmterm-7940-7960-sccp.8-1-2.cop.sgn have text:
Cisco IP Phone 7940 and 7960 firmware release 8.12(0) - Compatible Unified CM Versions: 5.1 or later
This one P0S3-8-12-00.zip
for 3rd party SIP call control environment
I know that I can use P0S3-8-12-00.zip,perhaps...but how I suppose that using this one cmterm-7940-7960-sccp.8-1-2.cop.sgn is more convenient?
Thank you a lot!
