[Freeswitch-users] Experience with SRTP

I'm running FS with TLS. This works. I would like to enable SRTP. Whenever I add that - either in vars.xml with rtp_secure_media=true or directly in my dialplan, then calls are dropped just after I'm answering them. I can still call subscribers, and the phone rings. When accepting the call it gets dropped with INCOMPATIBLE_DESTINATION. I have Bria on both ends.
