[Asterisk-Users] DTMF feedthru again...

[Doug Crompton]

Tried that makes no difference. Did it for you? What DMF method(s) are you
using. Looking at a goggle search yields lots of talk on this but no real
solution. Apparently there is an rfc2833 issue and * is working on it???
Also it appears the codec used might be an issue. This is a serious
problem in my book. It precludes me from using any DTMF over PSTN with *
at this point.

Any further help or explanation would be appreciated.
