If aleg is on IPv4 and bleg is on IPv6 then FS will allow that and
it'll handle putting the correct IPs in the SDPs itself. No extra work
required. A sip profile for each class, and bridge between them in
dialplan.

Yes, it does.

No support for BFCP.
FECC isn't supported natively, but should work in proxy_media mode
where FS doesn't need to know the codec, just forwards the RTP
straight through.
AFAIK, secondary video isn't supported. It might work in proxy_media
but probably not...

However, you might find you have a problem even with proxy_media...

I've only ever seen FS handling m=audio and m=video streams. I don't
know whether it would handle m=application ones.
