How can I debug SIP DTMF? If I do 'sip set debug peer xyz' I see no
messages related to DTMF... or if I just do a global SIP debug for
that matter.... I am using RFC DTMF but it's not being passed to the
PSTN and I need to debug this further. I've tried to increase the
verbosity and the debug ('set debug n') and that didn't help either.
I
assume this is because even RFC2833 sends the DTMF as RTP which
wouldn't show up anyways.... but how to troubleshoot DTMF issues?

If that's not enough information, I'd go into logger.conf and add "dtmf" to the logger and messages lines (and any others you care about), and then do a "logger reload" from the Asterisk CLI. -- Jared Smith Community Relations Manager Digium, Inc.
I think your best bet is to do a packet capture and look for RTP packets
with an RTP Event payload ("rtpevent" display filter).
