Oh, I forgot one thing;
I'm using fix_nated_sdp, as previously mentioned. I have a hunch that
because I'm not using force_rtp_proxy/rtpproxy_offer it's not being
relayed (a hunch, because I don't fully understand how rtpproxy
works). Problem is though, I can't get the IP addresses correct by
using rtpproxy_offer.
On behalf of Joe (same company) I will add that there is no NAT
scenario here. Both the private and public network are directly
routable from the rtpproxy box; there is no IP address
oversubscription, and no reason to ignore ports or addresses in SDP
and replace them with received parameters. This is not a far-end NAT
traversal solution.
What is basically being asked here is how to bridge between two
interfaces (internal, external) without NAT using rtpproxy, and if
anyone can provide a canonical implementation or example.
We've got it running in bridge mode, e.g.
rtpproxy -F -s udp:10.x.x.x:5050 -l 10.x.x.x/89.y.y.y
... and basically, are just wondering how to get this to work on the
Kamailio side using rtpproxy_offer()/rtpproxy_answer().
The RTP proxy machine is a dedicated host; the SIP proxies are virtual.
