[SR-Users] Problem with "transport=tcp" and rtpproxy

[Daniel-Constantin Mierla]

Based on the logs, there is no  check_route_param() executed. Actually,
it is an initial INVITE, doesn't have a to-tag, so there is no Route
header added previously by kamailio where check_route_param() can work on.

Looking at the headers, this initial INVITE has Via and Contact with
public addresses (maybe UA is using stun), only the SDP seems to have
carrier grand nat address. You have to adjust the parameter for
nat_uac_test() in order to detect it is a natted call.

Cheers,
Daniel
