Switching to 1.6.0 did the trick. I tried to run 1.6.0.28 but I had the no audio issue. I'm not sure what you mean by there is no 1.6.0. I found it here: http://downloads.asterisk.org/pub/telephony/asterisk/releases/asterisk-addons-1.6.0.tar.gz You're welcome to get with me out of band to see my specific setup. I am willing to post the traffic of the failing call with my asterisk 1.6.2 stack if anyone is interested. -stephan On Tue, Oct 5, 2010 at 9:20 AM, Kevin P.
