I hope someone can help me with this one... A few days ago we received a new 7937G. I installed the required s/w on CM, restarted the CM tftp-server, connected the 7937G to a POE port and.. it worked. That is, when calling/being called from an IP-phone. When calling/being called from an analogue phone the 7937G makes loud "squeeky" noises, even before the analogue phone aswers the call. The voice-signal is severely distorted.
The 7937-sccp.1-2-1 flash is also loaded in the 7937G.
Given the fact that the problems arise only when calling or being called from an analogue phone: is there something that needs to be done in our voicegateway?
