a) Before posting your issue you MUST answer to the questions otherwise it
will be rejected (invalid status) by us
b) Please check the issue tacker to avoid duplication
c) Please provide network capture (Wireshark) or Javascript console log
if you want quick response

What steps will reproduce the problem?
1.installed asterisk 11.7.0 w/o any error.
2.make calls frome Chrome to SIP phone
3.phone rings and connects but no rtp coming from chrome

What is the expected output? What do you see instead?
expected outcome is audio on both sides.. but rtp flows only one way i.e. from 
sip phone to chrome... no rtp from chrome to sip phone 

What version of the product are you using? On what operating system?
asterisk 11.7.0 on Slackware/Linux 13.37.0
chrome Version 27.0.1453.110 on Slackware/Linux 14.0
and one sip phone ( hard phone) connected to asterisk
and http://sipml5.org/call.htm

Please provide any additional information below.
calls from sip phone to other sip phone works fine with audio on both the 
sides.... But if we make calls from chrome browser to sip phone then rtp flows 
in one direction only... i.e. frome sip phone to chrome and no rtp from chrome 
to sip phone... audio on chrome side works fine and no audio in sip phone....

below is the snapshot of call made from chrome to sip phone

I'm running asterisk on EC2 and to make it working on both way audio, I 
manually patched asterisk's src/channels/chan_sip.c file to send the IP address 
of my EC2 machine.

It is in function: add_ice_to_sdp

Original Line: 
ast_str_append(a_buf, 0, "%s ", 
ast_sockaddr_stringify_host(&candidate->address));

New line: 
ast_str_append(a_buf, 0, "%s ", "[ec2-server-ip-address]");

That's the only way I found it to be working.

Hi,

I'm facing the same situation, then my asterisk server is behind nat (required 
ports are forwarded). My Sipml5 + Chromium 34 has sound, but I can't hear 
anything on my Cisco phone. rtp debug on asterisk shows bidirectional rtp 
stream, but if it try to analize packets with wireshark i can see normal rtp 
packets flowing from asterisk to Chromium, and only UDP STUN request packets 
flowing from Chromium to asterisk. This mens that ICE session is not 
established and don't know how to fix it...
