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

@dimas - I did some testing with the patch.  Unfortunately, it didn't
correct the issue. It actually broke some scenarios which were working
under 1.4.24.  I attached a file with DTMF debugging as well as your 'ugly'
comments :)  If I need to provide actual RTP debug, let me know... but I am
guessing this will suffice.  The overview of the test results are:

****** Test:  http://bugs.digium.com/view.php?id=1 
****** Result: SUCCESS
****** Phone: Aastra IP phone connected directly to Asterisk
****** DTMF Entered: 123
****** DTMF Recieved by Read application: 123
****** Notes: This scenario worked fine in 1.4.24


****** Test:  http://bugs.digium.com/view.php?id=2 
****** Result: FAILURE
****** Phone: Landline Home Phone
****** DTMF Entered: 123#
****** DTMF Recieved by Read application: 111222333
****** Notes: This scenario worked fine in 1.4.24 but is now BROKEN in
1.4.24.1 w/ supplied patch


****** Test:  http://bugs.digium.com/view.php?id=3 
****** Result: FAILURE
****** Phone: Cellular Phone - Blackberry Curve - T-Mobile
****** DTMF Entered: 123#
****** DTMF Recieved by Read application: 1122333
****** Notes: This scenario did NOT work 1.4.24 and is still BROKEN in
1.4.24.1 w/ supplied patch

Thanks!
