Hello, everyone. I have tested imsdroid, idoubs and boghe with asterisk and kamailio. They all worked well when audio calling and video calling. Doubango projects are great. Thanks...
Because my sip clients work behind nat, I enable stun/turn option. The asterisk/kamailio server acts as both sip proxy and media proxy. Server becomes performance bottleneck. When two sip clients use video calling, the video stream's quality is poor. So I try to find out a solution that two sip client behind nat can take on directed video calling without server forwarding the video packet. I have search the web, but has few result. Anyone can give me some suggests? Thanks

Enable ICE in sip clients and enable directmedia=yes, directrtpsetup=yes in asterisk. This should help solve the problem. :-)

Thank for your reply. I have tested the solution. But using wireshark, the media packet is forwarded by asterisk.

Because your Asterisk server is removing the ICE candidates. You will
have the same problem with all SIP clients.
To confirm, please attach the wireshark trace.
