I am taking in a call from a VOIP customer through a Cisco 7300 and terminating this out to a Tier 1 carrier. It appears the the DTMF tones are being distorted or not recognized and the problem is arising in my Cisco. I have heard that it is recommended that I use g711, unfortunately this is not possible. I have also ensured that the command: dtmf-relay h245-alphanumeric is being used in the corresponding dial-peer. Can anyone help me with this problem? Any input is gladly appreciated.
