[asterisk-users] DTMF Tones

[Jason Walker]

I have tried beta2, beta3 and now back to 1.2.12.1 and I have correct 
DTMF tones 25% of the time.  I have to call several times to enter an 
extension.  I have a router and a packet shaper and some other stuff. 
Anyone have any other ideas why this might happen.  I do not have any 
Zap channels but I am running CentOS4. I also do not have any cards 
installed. Thanks
