Hello,
I'm using below routing logic to change the 183 reply to 180 and send it
back to the origination.
Noting that Kamailio is listening on 5065.
route{
if (is_method("INVITE")) {
xlog("L_INFO","INSIDE request route $si \n");
insert_hf("X-AUTH-IP: $si\r\n");
}
route(FWD);
}
reply_route {
#xlog("L_INFO","INSDE reply \n");
if (status == "183") {
change_reply_status(180, "Ringing");
exit;
}
}
route[FWD] {
#xlog("L_INFO","INSIDE FWD \n");
forward(x.x.x.x,5060);
}
Below is the scenario , where the customer is sending packets to Kamailio ,
and Kamailio is forwarding them the supplier (with IP x.x.x.x) , then the
supplier reply back to kamailio and kamailio relay the reply to the
customer
----Customer---- --> ----Kamailio ---> ---Supplier---
I have a case where the supplier sends in some cases an in-dialog invite
(Re-Invite) , which is considered I think as SIP-Request and thus as per
above routing logic , kamailio is sending it back to the supplier , yet I
need to send it to the customer.
How can I solve this issue?
Thanks

Hi,
In-dialog requests must be handled using loose_route(). You can find the
proper boilerplate in the stock configuration file:
https://github.com/kamailio/kamailio/blob/master/etc/kamailio.cfg#L587
To note, your config is not sufficient to handle all aspects of a call
between endpoints in an adequate way. You will want to consider the main
request_route in the main config file and adapt its most essential
aspects accordingly:
https://github.com/kamailio/kamailio/blob/master/etc/kamailio.cfg#L455

Hi Alex,
So loose_route() is only responsible of In-dialog requests ?
Can you please send me a simplified config that suit my case ?
Noting that I'm using Kamailio only as proxy between my customer and my supplier.
Much appreciated.

Hi Alex,
Thank you for your reply.
Does below config forward all sip requests coming from the customer to the supplier , and
relay sip replies back to customer ?
Where re-invite packets are handled in the below config file?
Thank you

ReInvites like all in-dialog requests are processed in has_totag()/loose_route part.
Default kamailio.cfg has almost identical part for this purpose.
Main idea is that an initial request (non in-dialog) hasn't To tag already. It appears
only when your request "hits" remote side (called or callee, as you wish) and
goes back to you. Simplified, but I hope you got an idea :)

Thank you for your reply.
I tried the config file shared by Alex below , but I noticed that kamailio is not dealing
with CANCEL requests.
the scenario in my case is that I’m using Kamailio behind a switch to alter some packets
(precisely 183 packets) , so I need to forward all packets coming from my customer to the
switch , which will deal with it (send it to appropriate supplier).
So what I need is the config file that will forward all requests coming to Kamailio from
my customer , to forward them to my switch , then reply back to customer the reply coming
from the switch. 9after altering 183 packet to 180) , handling the in-dialog invites sent
by my switch , which needs to be sent to the customer by kamailio.
Thanks
