I am calling a customer and we are getting one way audio - we can hear them, they cannot hear us. Also, when their AA picks up it is not recognizing DTMF input. This is only happening on this one customer number and I suspect it is on their end, however I want to make sure that the problem is not us. I have asked Telco to review call details and check out T1 and they reported no problems found (yet..). Any suggestions to help me verify it is not us?
We are running ICS7750 w/ CM 3.0(8). Gateways are using IOS build 12.2(1)XD1, phones are 7960, and calls are going out over a dedicated voice T1 CAS
Make sure that on your gateway (cisco IOS box) that routing is enabled. If not this will result in single way voice. Make sure the "ip routing" command is visible in the running config. This may sound very stupid, but you can easilly look over it, especially if the box only has a single ethernet interface and therefore should not do routing. But nevertheless "ip routing" should be enabled.

the softkeys. You enable or disable them via TCL. Here is the long
