Summary:                    [patch] dtmf creating double digits if received out
of order
Description: 
Have an Adtran TotalAccess 916e with MLPPP bonded t1's registering with sip
to an asterisk PBX (Asterisk 1.4.26.1 on centos 5.2). Sip channels set up
for dtmfmode RFC2833 and codec is g729. The devices calling through the
adtran are unable to send DTMF correctly to remove IVR's or even to
applications on the Asterisk PBX 99% of the time. I created a ticket and
capture with Adtran and their response was that perhaps asterisk cannot
handle out of order DTMF packets. Their response is in additional
information.

well customer says the no longer have problems contacting the physician's
paging system when we asked them to test. Before, when interleaved, they
could never page the doctors when calling up a service. We've left the
customer on fragmentation/interleave throughout the day without issue. I'm
leaving the customer this way until they report an issue. Hopefully this
fixed it. Given the nature of the fix, it might also fix it so that I don't
have to dial dtmf slowly on an ip handset to make sure it works.
