asterisk users - Jan 2006 - DTMF's indescipherable, but voice clean!

After many hours today thinking that I had placed a bug into my dialplan, I
realized that for some reason DTMF tones are simply not making it into
asterisk! Calling into my pbx transmits crystal-clear audio in both
directions. But dialing DTMF's from pstn->pbx is unsuccessful, while
pbx->pstn works fine. The tones simply don't make it through. Tiny brief
fragments are all.

Please listen to the linked audio clip if this doesn't make any sense. I
don't know what to do.

How are you connected to the PSTN?

-A.

It might help to describe what interfaces your Asterisk PBX with the PSTN.
Is this a VoIP provider DID you are using, or a POTS line with an interface
card, or a PRI with a digital interface card?
