[asterisk-dev] DTMF Issues Version 1.6.1.20

When we disable g729. This issue goes away. Why would asterisk be having an 
issue with rfc2833 and g729 with in call dtmf?

Thanks
Bryant

Asterisk version 1.6.1.20
I am having an issue where in call DTMF seems to degrade over time. When 
calling into thirdparty IVR systems through several different SIP providers 
some of the DTMF tones are being doubled. We are running rfc2833 for the 
DTMF. I have tried with relaxdtmf both on and off. When I restart asterisk 
the issue goes away but comes back several weeks later. This does not occur 
on our asterisk 1.4.x boxes. Nor does it occur when placing the calls out 
through an audiocodes pri gateway. 

Any ideas on what could be causing this. Was this a known issue with this 
1.6.1.x versions? Would moving to the 1.6.2.x version fix it?

Thanks
Bryant
