Yes, as said, the first server should use "send()" function instead of
"t_relay()" -> it will be skipped by the reply.

Thanks for the response. What I am trying to do is to have the first
proxy route the request to the second proxy server that will actually
process the request. In this case I have another opensips server that
I want to just handle register requests. This proxy server would then
send the replies back to the client and not the first proxy server. Is
this the idea way of performing this functionality? I was trying to
separate some functions to separate sip servers ( a sip server for
registrations, another sip server for pstn gateway, etc) but have a
central point of entry.
Thanks

Hi Nathaniel,
According to SIP RFC, replies are following the same path as requests
(in revert order, of course) - this back routing is done based on VIA
hdr (added in requests, consumed from replies).
if you want to avoid opensips to add the VIA hdr (so, to be skipped
by replies), use the send() function for relaying the requests - be
careful this is a stateless function, so no failure_route !

Hello,
I would like to know if this routing is possible and if so how. I
have a scenario where I have a opensips proxy that I want to use
just to send requests to other opensips proxy witch would then
process the request. Here is the scenario: client --> p1 --> p2
--> client --> p2. I have been able to route to proxy 2 but the
replies are still being routed back via proxy 1 then to the client.
I was hoping to send the replies directly to the client and not back
thru the first proxy. Is this possible? I am currently using the
dispatcher module to send the requests to the second proxy. I also
noticed that the SIP packets have a VIA header of the first proxies
IP address when it reaches the second proxy. I thought the
record_route was causing this, so I moved it after I send the
request to the second proxy. Here is a small snipet of my code:
if (is_method("REGISTER")) {
if (!ds_select_dst("2", "3")) {
sl_send_reply("503", "Rawr!!");
};
t_relay();
}
Thanks
Nathaniel
