Description:Using AGI's Record File with DTMF Termination leaves a bit of the DTMF used to terminate in the recording at the end.

If a recording is ended with DTMF, it's probably best to lop off the last 100 ms or 200 ms to remove the tone fragment.


This problem has always existed, and it's always bothered me, but one of our customers has been complaining about this, so I was motivated to file a bug on it.

To hear an example, call +1 619 364 0221.  You'll hear a bit of DTMF at the end of each prompt.

Fixed in CVS HEAD.

This would only affect inband DTMF users, but it seems reasonable to drop the last 200ms of the recording in any case.
