i don't know how this would help.  proxy gets invite that includes ipv4
or ipv6 address in sdp and $rd is domain name.  what should proxy config
do?

in such situations perhaps rtpproxy should ADD its own address of
different protocol in sdp and then when reply comes, un-arm rtpproxy if
reply included address of original protocol.

i don't know if legacy UAs can deal with two ip addresses in sdp.  if
not, this whole bridging stuff is wasted effort.
