5. Your problem:
Brekeke SIP server can not support media relay for nat transversal with BFCP. When endpoints in private network send content, the SIP server receive the main video and content RTP stream at the same udp port, that cause the other endpoints can not decode the video and conetent.
We have test Polycom M100、Polycom RealPresence Desktop、HUAWEI TE30 and got the same issue. When in the same network without NAT, BFCP is work with Brekeke. Polycom M100、Polycom RealPresence Desktop、HUAWEI TE30 can send&receive content by BFCP.
