| Okay, change the dtmf-relay from H245 to none and try sending it in-band,
however, if you are using a low-bandwidth codec (G.729, etc...) this will
distort the DTMF.

As Scott said, the alternative is to use MGCP, which is pretty adept at
transmitting DTMF, but that presumes a CallManager that may or may not be
present.
Also, this is receiving or sending DTMF on the gateway? (IOW, are you
sending DTMF out a PRI, or receiving it from a PRI?)
What is the config on the voice-port for the PRI?
