This started working - but the problem is that it's matching both sides of
the conversation. I'm searching for a concrete method to say "only if
you're going to send this packet to the upstream provider" but the closest I
found was "is_destination" which has to be called from loose_route, and
unfortunately it looks like we don't have any HF setup for this particular
situation, so loose_route always returns 0 and exits (confirmed in the
logs).
The provider won't let me add stuff - maybe I can just add stuff one-way
then rip it off on the return?
if (is_method("INVITE") && status=="200" && $(ct.fields(uri){s.substr,4,12})
!~ '^8150*') {
xlog("L_INFO", "Modifying the outbound
Contact header to Carrier... $(ct.fields(uri){s.substr,5,12})");
subst('/^Contact:(.*)sip:[^@]*@[a-zA-Z0-9.]+(.*)$/Contact:
<sip:$avp(oriUri)@192.168.0.2>/ig');
}
Any tips?
