We are running CCM 4.1(3).
We are facing problem on some of the IP Phones(7940), like receiver of these phones are not working.You can only able to hear the voice from Speaker mode.
While ringing if receiver goes off-hook, still the rings are continued untill we press speaker phone to pick up the call.
I feel there is no off-hook signal for the receiver...
Any suggestions to resolve this problem...
