[OpenSIPS-Users] Rtpproxy and IPV4 IPV6 interworking

I have some question regarding rtpproxy capabilities in relation to IPV4-IPV6 

The articles I have read say that you need to assign an address from each 
address family to rtpproxy. They go on to say that rtpproxy will then be in 
bridged mode. Others define bridge mode as assigning two interfaces to 
If the IPV4 and IPV6 addresses are on the same interface, is the rtpproxy 
indeed in bridged mode? Should one avoid the use of engage_rtpproxy?

Assuming that IPV4- IPV6 interworking is actually possible using opensips and 
rtpproxy, does that mean that an instance of rtpproxy is not available to 
enable NAT traversal - would NAT traversal require using another instance of 
rtpproxy using a single IPV4 address?

Furthermore is the multihome parameter relevant to IPV4-IPV6 interworking if 
opensips only listens on one interface?

Thank you all
