New Option: "x" for automatic bridging
between IPv4 and IPv6.
Based on the following assumption: "i" is the IPv4 interface
and "e" is the IPv6 interface on the RTPProxy (tested with both
RTPProxy and Sipwise's ngcp-mediaproxy-ng).
Mechanism is as follows:
- IP in SDP is IPv4: Do bridging "ie"
- IP in SDP is IPv6: Do bridging "ei"
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.
