<div>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.<br>
<br>
</div>
<div>Anyone has any ideas? Kamailio 4.3, FS 1.4<br>

I assume you use rtpengine just to proxy media, afaik, no zrtp
decryption/encryption support for it yet.<br>
<br>
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.<br>
<br>
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.<br>
<br>
