[Freeswitch-users] Terminating ZRTP call over two FS's bridge.

I have two FS's (FS1, FS2) with ZRTP enable in two sites.
I can make end-to-end ZRTP calls between two CSipSimple/ZRTP clients over
the two FS's bridge where both FS's are set to 'proxy_media=true'.
CSipSimple -> FS1 ---Internet -à FS2 -> CSipSimple.
Now I connected a PBX to each FS with SIP-Trunk.
PBX -> FS1 ------- FS2 -> PBX.
When calling locally from CSipSimple to a PBX extension on the same FS then
the ZRTP is terminated by the FS as MITM which is OK (FS dialplan
What I cannot figure out is how to terminate ZRTP call between
CSipSimple/FS1 and FS2/PBX.ext and vice versa.
CSipSimple -> FS1 ------- FS2 -> PBX.ext.
I've tried to setup:
FS1 with 'proxy_media=true' (passthrough ZRTP) + FS2 with
'proxy_media=false' (terminate ZRTP).
FS1 and FS2 with 'proxy_media=false' .
All results with ' ZRTP not negotiated on both sides; disabling ZRTP
Any help will be appreciated.
