Dear All
I don't understand why in the Openser+MediaProxy i need
record_route_preset("x.x.x.x:5060;nat=yes"); and search("^Route:.*;nat=yes")
What is the purpose while I can do client_nat_test to see if the request is come from a nat-ed client.
If I remove search("^Route:.*;nat=yes") from below statement, I can do re-INVITE without any problem because it still have client_nat_test to find out the nat in between.
if (client_nat_test("3") || search("^Route:.*;nat=yes")) {
setbflag(6);
use_media_proxy();
};
Hope someone can give me a clue.
Thank you.
Regards,
Halomoan

Hi Halomoan,
Mainly because the NAT detection on SIP replied is very poor
- you can
check only if the contact address is a private one or not.
The other nat
test are not applicable for replies (but only for
requests).
Anthow, when you process the request, you learn that the
calee is behind
NAT, so you can simple remember this (in RR) than detecting
it each time
when receiving a reply.

bogdan

Hi Halomoan,
loose_route() only marks the Route hdr to be deleted when
the message is
sent out (it does not actually delete the hdr). So, the
search after
loose_route() should work, but it look a bit broken to me,
as it will
check all the Route hdrs and not only the one belonging to
the server.
regards,
bogdan

Hi Bodan
I understand your explaination for loose_route(). but you
said it will
check all Route hdrs? I thought it should only check 1 line
at a time,
so remove only the Route hdrs that belong to it, right?
I think to fully understand openser, you got to have a
complete sample
message of SIP in different dialog/session and in different
condition
