[Asterisk-Dev] The Almighty X-Lite DTMF Problem

[Chris Heiser]

Pete,

Try this patch below...  I noticed that eStara's softphone has the same
problem as xten's softphone when it comes to DTMF.  Seems as though Asterisk
is not looking for the "end" bit per RFC2833.  So try this fix.  It should
do the trick (at least... it fixed mine).
