via that guide.
Kamailio and FS are on same host on Amazon EC2. The issue is - when I
have proxy_media=true on FS, ZRTP is OK, but the leg_b user can't hear
anything (but his voice is transmitted OK). When I set proxy-media to
false the voice is OK, but something is with ZRTP so Jitsi can't
establish ZRTP handshake. When I set bypass-media=true on FS both ZRTP
and voice established, but quality is sometimes bad and the delay is
too big.
Anyone has any ideas? Kamailio 4.3, FS 1.4
I assume you use rtpengine just to proxy
media, afaik, no zrtp
decryption/encryption support for it yet.
From my point of view, the troubleshooting has to be
done in freeswitch,
when it is involved in the media path -- try to run it with
higher debug
level.
You mentioned that there is delay when freeswitch is bypassed for media
-- for this case you have to test the latency to rtpengine, sometimes
the virtual machines performs bad when they deal with a lot of small
network packets.
Cheers,
Daniel
