[asterisk-dev] IAX JB DTMF Issues

[Greg Boehnlein]

Hello,
	I have been having DTMF issues between a pair of 
SVN-branch-1.2-r37949 boxen. Basically, with jitterbuffer=yes on both 
hosts, DTMF doesn't work. Server A sends the DTMF to Server B, and an "iax 
debug" confirms that the DTMF is received, but it is never passed on to 
the IVR.

Setting "jitterbuffer=no" on both boxes solves the problem and allows DTMF 
to work reliably.

There is currently a bug open, http://bugs.digium.com/view.php?id=6011

There are a few others that have been closed and reference back to this 
bug.

Am I going insane? Or is DTMF really horked? :)
