Thanks for reply
So I attached 2 log files:
1 from chrome to ff with no audio
2 from ff to chrome with ok audio

About ip address:
1.1.1.1 - kamailio server with rtpengine
2.2.2.2 - asterisk media server.
It runs as 
./rtpengine --ip=1.1.1.1 --listen-udp=127.0.0.1:7723 --listen-ng=127.0.0.1:7724 --pidfile=/var/run/rtpengine.pid

ringing between 2 peers thats behind NATs on both sides
mycompany.device-1884 at 3.3.3.3 (at chrome  35.0.1916.153 m)
mycompany.device-1091 at 4.4.4.4 (at ff  30 )

so when ring from chrome to ff at asterisk I i see rtp debug that displays this:

We we use jssip.net demo from theys site.

Thanks very match and sorry for my bad English.

P. S. Log files also have kamailio log messages, if you do not need it just do not pay attension to this.

Hello. I have Kamailio 4.1.3+rtpengine_rtpproxy-ng as module for rtpengine.

Kamailio installed as frontend (registration, auth, proxy ) of
asterisksk servers.

WEBRTC users registred at kamailio and asterisk works as media server.

When I try to call from Jssip from Firefox to chrome to way audio is fine.
When I call from chrome - I see rtp packets only from firefox. Not from
chrome.

At kamailio log when I call from chrome log the same as whe i try to
call from firefox (I can not see anithing wrong)

It would help to have the complete log messages from rtpengine. Make sure you have a very recent version of Firefox, it used to have certain WebRTC implementation problems.

cheers
