Summary:                    DTMF Appears to be broken from certain sources on
asterisk 1.4.24 - double digit.
Description: 
I am having some trouble with 1.4.24.  This appears to be a regression
since 1.4.21.1 as I have just recently upgraded and started to experience
the problem.

When calling my asterisk box from a cell phone the system detects double
DTMF digits.  When calling from a landline or pure SIP device DTMF
detection works fine.  I have determined that the cell phone is sending the
RTP DTMF payload about 2x more than the other devices, but as far as I can
tell it should still be considered a single digit as per the RFC.

Attached are two TXT files of pcap exports which show the dump for a
working DTMF interaction, and one for a failure situation.

Please let me know if I can provide any further information.

Thanks,
Geoff

OK, I have made the requested change and retested scenario
http://bugs.digium.com/view.php?id=2 and http://bugs.digium.com/view.php?id=3,
they
are more broken now than before.  Please see the _v3 test result TXT file.

p.s... i find it very strange that I just happened to upload all 3 files
at :34 minutes past the hour for three hours straight now.  I think I'll
play the lottery tomorrow. :)
