I have a MCS 7815 with preloaded CCM 5.0 and 50 Cisco 7940 IP phones.
With the basic configuration all 50 IP phones are communicating fine.
My problem is, I am unable to activate the messages and "help ?" key. What configuration should I do in the CCM to activate messages and "?" button. I should be able to send messages within my 50 Ip phones. Please help...
