Hi,
Yes, you are right - and I agree, it would be better if this was possible :)

Hello,
It'd be better if the "add_path()" function could be used here. That way,
if using outbound (RFC5626), the flow-token (the userinfo part of the
Path-URI) would be present and there would be no need to add the
";received" parameter.
This would address the one issue remaining for SIP outbound on Kamailio,
which is its use without an edge proxy that is separate from the registrar.
Regards,
Peter

Hi,
This sounds like a case for sharing same database, and adding Path before
saving incoming register. That way, no need to replicate register message
to other servers and all subscribers use the same domain.
Add path something like this before calling save():
append_hf("Path: <sip:$Ri:$Rp;
received=sip:$si:$sp;lr>\r\n");
msg_apply_changes();
Whichever server receives the incoming invite, will perform lookup and
automatically route to the server which received the register. On the
proxying server set $du according to received param of route header, add
record-route, and then t_relay(). As Daniel said, no need to
re-authenticate or perform lookup again.
Regards,
Charles

Suppose I have three or more kamailio servers. If a call comes in and
lookup() returns that no record was found, how do I know which server to
forward to? Is that a case in which I should replicate the database?
I currently have two independent kamailio
servers. I'd like to set them
up in a way that user1 on server1 can make a call to user2 on server2.
After searching I've come up with two ways that this might be able to be
done. Can someone please sanity check these or point me in the right
direction?
1. Have one registrar server and convert the other server to a proxy
2. Keep them both as registrars and somehow make them each aware of the
users on the other server
I like 2 better because if one server went down users on the other
server would still be up. The only thing is I don't know how to set the
servers up to communicate with each other.
the nat can create problems when a server is down - if the nat is
symmetric, only the server that received the registrar can send back calls
to the phone.
Communication between users on two servers is as simple as using
t_relay_to("proto:serverip:**port") after you do lookup("location")
and
no record is found. You have to add an extra check for the case the
call was coming from the
other server, not to forward back to it in case of no found again.
Thanks for the tip, I hadn't thought of that.
Also, you should skip user authentication for
calls from the other
server (not do authenticate twice). Another aspect to take care is chaining
rtpproxy, you have to use the flat for trusting the other server (r, iirc).
You can also replicate the registration, but again, it can add troubles
to the nat. Look at t_replicate() (in tm module).
Cheers,
Daniel
