I've just set up CCM3.0 and a 3600 gateway to test VOIP. The configurations is basic:
- 3600 gateway with a 2 port FXO vic connected to two pots lines.
- 3524 XL switch
- several IP phones connected to the switch.
We have the basic functionality working, but I am having an issue with passing DTMF tones to our IVR (voicemail) system. Everything I read states that I have to turn up an DTMF Relay, but I can't find anything that shows me how. Can anyone point me in the right direction?
