No Audio at all after updating to latest Asterisk Patch about sipml5 HOT 6 OPEN

I looks like your Asterisk server is running on private network (not public). 
Is it right?

It's on an EC2 server, and it's publicly accessible. As for the Chrome clients, 
they are of course behind NAT.

Update on this issue:  I installed Asterisk 372699 and applied the patch on my 
laptop, which runs Ubuntu 12.04 64 bit.  I first tried with the configuration 
used in http://code.google.com/p/sipml5/wiki/Asterisk#Building_source_code and 
then experimented with some of the settings like nat, icecupport, tcpenabled, 
and other various settings.

I installed on my local PC to try and eliminate NAT as an issue. I was hoping 
that having the 2 Chrome clients and Asterisk behind the same private network 
might help.  It didn't. I get the same error as originally reported:

[Sep 14 00:20:49] ERROR[7196][C-00000002]: netsock2.c:269 ast_sockaddr_resolve: 
getaddrinfo("df7jal23ls0d.invalid", "(null)", ...): Name or service not known

I also want to point out that this was a bug I reported to the Asterisk issue 
tracker. The bug was fixed in revision 371483. Is this bug back, or is 
something else going on? I'm considering reporting this to the Asterisk mailing 
list as well. What do you think?

hi every one .. 
is still no solution for this problem !!?

This issue seems no solution.
