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.
