Hello,
I'm using Kamailio in a Multi Domain setting.
I have a problem with SUBSCRIBE within a Dialog
With the first subscribe no problem:
SUBSCRIBE -> 407 Proxy Auth -> SUBSCRIBE -> 200 OK
In the 200 OK the Contact header contain the Kamailio IP so when the
Softphone send another SUBSCRIBE within the dialog (at the IP present
on the contact header) Kamailio answer whit a 404 Not Here because I
use these lines:
if (is_method("SUBSCRIBE") && is_uri_host_local()) {
# in-dialog subscribe requests
route(PRESENCE);
exit;
}
So, as the softphone send the new SUBSCRIBE to Kamailio IP and not the
Kamailio domain, Kamailio not use this block but:
sl_send_reply("404","Not here");
exit;
}
My question is: Why Kamailio in the Contact Header of 200 OK of
SUBSCRIBE use the public IP and not the domain?
a dialog is typically established between two endpoints, which are
better identified by an IP address, behind a domain can be many ip
addresses, which can result on requests within dialog being routed to a
different server. If you have only one, set the server_address parameter
to presence module to what you want:

You can also change the condition so it uses (uri==myself ||
is_uri_host_local()).
Cheers,
Daniel
