Summary:                    [patch] 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
