[cisco-voip] Re: dtmf on h.323 truck to avaya Definity s8700

Ok, under the gateway setting try checking the "MTP required" box.  It
my well be that the feature negotiation, when initiated from CM doesn't
get an answer it likes.  The MTP usually can cure problems like this.

s8700

Running 4.1 which has fast start under the gateway settings now. I had
to enable fast start on outgoing calls before I could even get the link
to the s8700 working. Could never get it to work in 4.0.

Prior to enabling fast start, call control would work, but the audio
codec/setup would never negotiate so I could never get an audio path up
when the CM would initate a call to the 8700. Again in this situation a
call orignating from the 8700 would work fine.
