Description:DTMF will get misinterpreted frequently or pass along incorrect values when using a build of Asterisk 1.4.41 on outbound calls.

We have tried dialing our office pbx (running Asterisk 1.4.39) and Bank of America to test the outbound DTMF functionality.

Asterisk is running on Gentoo in an OpenVZ container environment running CentOS.  We are not able to reproduce with this issue with releases we have used in the past (1.4.39, 1.4.35 or 1.4.26) in the same environment.


We have opened a ticket on our bug tracker tracking this issue:

Attaching "CCS_BT_0000019_DTMFissue_vanilla_1.4.41.pcap".

This is a trace of vanilla Asterisk 1.4.41 from Digium reproducing the issue by

1) dialing 14044782200 and attempting to dial '207' at the IVR prompt to dial extension 207.
2) dialing 18002884408 and attempting to dial '1' at the IVR prompt to choose English option from IVR.
