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

lmadsen,
in case of moliveras it is the configuration issue. However in the case of
geoff2010 it is not. His case can not be solved by just configuration...


geoff2010,
sure.
