good day
I have 10 IP Phones type 7975G, I tested the following 4 firmware on my CCME 8.6:
cmterm-7975-sccp.8-3-3
cmterm-7975-sccp.8-3-4SR1
cmterm-7975-sccp.8-3-5
cmterm-7975-sccp.8-4-2
But IP phones do not accept any.
I have downloaded all the firmware from Cisco, but they are many how can I identify the correct firmware for my IP IPnone 7975?
best regards,
