What is your setup, hardware wise?
If you have the digium cards- FXO or FXS, you must make sure you tune them. I
had issues with DTMF's, when I went live with my Asterisk system. Once I tune
them, everything worked great.

Subject: [asterisk-users] Unusual DTMF behavior
We are having an issue where DTMF is not being sent out right away and the tone
duration is inconsistent. For a test we send a '5', then a second later we
send a '9', and then five seconds later we send a '5'. If you look at the logs
below you can see the first '5' is played right away, then the '9' comes in and
gets queued, but it doesn't start playing until five seconds later and it plays
for six seconds. Then the last '5' is played.
The DTMF is coming in as only 'end' packets and we can't change that. For this
reason we have turned on rfc2833compensate. Using Asterisk 1.4.11.
Any ideas?
