A tutorial I wrote for bridging IPv4 and IPv6 can be useful to go through:

- http://kb.asipto.com/kamailio:kamailio-mixed-ipv4-ipv6

It show bridging of sip and rtp between not directly routable networks.

Instead of doing kamailio.cfg rtpproxy_manage() decisions on af (address
family), it has to be done on dst_ip (local ip on which the packet was
received) and rtp proxy started with "-l ip1/ip2" instead of "-l ip1 -6
/ip2".

Cheers,
Daniel
