[Asterisk-Users] DTMF Digits

[Brian J. Schrock]

Hello,

I am having a problem with Asterisk that I just cannot get fixed... 
When I call in to the main number I have to wait until well into the 
second message shown in the extensions.conf snippet below to enter an 
extension number. If I enter digits really slowly sometimes it will 
work during the first message. Usually my callers just get the 
incredibly annoying "invalid message recording". I remember reading on 
here about DTMF detection problems earlier, but cannot find anything 
relevant. Has anyone else had this problem, or does anyone else know 
what could be the problem?

My extension are all 2244,2245,and 2246. If I enter 2244 too early in 
the playback Asterisk recognizes it as 222 or sometimes 24.

If I unload the zap drivers and reload them and restart asterisk it 
will work just fine for the first call but after that the problem shows 
up.

If I play with txgain and rxgain enough I  can make the problem worse 
but not better.

My asterisk is from cvs two days ago.

I have been turning echo cancellation on and off in different 
combinations to see how it affects everything, and it did not have an 
impact.
