[Freeswitch-users] Different DTMF behavior???

[Michael Collins]

Do you have pcaps of the traffic for working and non-working DTMFs? Until
you do you won't have a clear picture of what is actually happening. You'll
want to check the SDP that's negotiated as well as look at the RTP stream
for DTMFs. If they send RFC2833 you'll actually see them show up in
Wireshark's "flow" diagram. If they're in the audio then you'll need to use
the "player" tool and listen to the audio streams - assuming you're using
g.711, of course. (Wireshark only does g.711...)
