necessary to use the cwie / cwei flags in the rtpproxy_manage call?
If rtpproxy uses only a single listen-IP, then these flags are not
needed. Only if you operate rtpproxy in bridge mode, then you need these
flags. Bridge mode is necessary if you do not have IP routing between
the internal network and the "virtual external" network, or if you want
to bridge between IPv4 and IPv6.
John,
This function can be used to check the direction of every message:
http://kamailio.org/docs/modules/4.0.x/modules/rr.html#idp223296
You might also need to append the record-route parameters to remember
the flags you have passed to the manage_rtpproxy() initially.
Based on the direction of the request and initial flags you can
determine what flags to use when calling manage_rtpproxy() for a given
in-dialog requests and reply.
Hope this helps.
Andrew
Are the calls being bridged across two interfaces or is the Kamailio
just natted? (or is it both?)
