Greetings...
I'm working on getting an AudioCodes Mediant 2000 big box o' PRI's
going
with Asterisk, and am running into a problem with DTMF handling.
The box is sending DTMF packets to Asterisk as INFO packets, and they are
apparently being seen by Asterisk. However, the DTMF knowledge doesn't
seem to actually do anything -- the VM system doesn't recognize the
digits, and if I call a SIP phone from the outside world, the beeps don't
make it through.
Here's what the packets look like, according to sip debug:
Sip read:

My sip.conf entry looks like the following:
[rochny-audiocodes1]
type=friend
host=208.34.86.37
dtmfmode=info
secret=[mumble]
context=inbound
I've tried various settings for dtmfmode, there and in the [general]
section, to no avail.
Any help or troubleshooting tips would be appreciated. Thanks! :-) -rt
