[Freeswitch-users] zrtp passthrough

I need to set up a passthrough zrtp in freeswitch. I followed this wiki: http://wiki.freeswitch.org/wiki/ZRTP and setup two Jitsi softphones. MiTM: works well but with different SAS in the softphones. It is ok because of a missing zrtp enrollment process. Passthrough: no SAS at all and Jitsi says the media is not encrypted I tried to achieve passthrough by uncommenting sip_profiles/internal.xml: <param name="inbound-proxy-media" value="true"/> What is the proper way to set up passthrough zrtp and having an end-to-end zrtp session with the same SAS on both softphones? Thank you, Peter
