Hello Saul, I was looking at a SIP trace on an active call as I type this. Actually we only need the public ip address advertised in the SDP payload for the device which is behind NAT (ie, listening on a private ip address with 1to1 port forwarded mapping done on the router for the public ip address).
The advertised address of the VIA and Contact headers are what shuffle between public and private IP addresses. This of course is the handled by OpenSIPS as it already does so eg: Via: SIP/2.0/UDP 74.71.33.154:5060;branch=z9hG4bK4.0. Contact: <sip:74.71.33.154:5060;did=5f7.8d>. Via: SIP/2.0/UDP 192.168.0.100:5060;branch=z9hG4bK596;rport. Contact: <sip:192.168.0.200:5080;did=5f7.8d61> In summary, can you kindly direct us to the much needed documentation on how to install, configure, and run an OpenSIPS+MediaProxy instance from behind a natted 1to1 mapped instance. Only upon doing so will I resume doing jumping jacks which I have halted indefinitely until further clarity. Kind Regards :) Nick. _______________________________________________ Users mailing list [email protected] http://lists.opensips.org/cgi-bin/mailman/listinfo/users
