Thanks
Daniel. I got it basically working with the following
config. But there is one last bug. If client B connected
and registered, then disconnected without proper unregister,
it seems the location table didn’t get prompt update. If
client A sends Invite right after that, the sip server will
try to connect to B(which will surely fail since B is behind
the firewall), instead of sending 480 to A right away. Is
there a way to fix this?
Thanks.

if
(is_method("REGISTER"))
{
# authenticate the REGISTER requests (uncomment to enable
auth)
if (!www_authorize("", "subscriber"))
{
www_challenge("", "0");
exit;
}
if (!db_check_to())
{
sl_send_reply("403","Forbidden auth ID");
exit;
}
if (!save("location", "m"))
sl_reply_error();
exit;
}
if (!lookup("location")) {
#if (!registered("location")) {
sl_send_reply("480","Not Found");
exit;
}
if (!registered("location")) {
sl_send_reply("480","Not Found");
exit;
}
if(!t_relay()) {
sl_send_reply("500", "relaying failed");
}
exit;

Hi,
I
am really new to ser(just installed it today). My situation
is here:
Both
A and B make tcp connection to ser proxy server. If A sends
“Invite” to B, ser would look up the tcp connection of B,
and relay the sip request. If B is not connected, then 480
is returned to A. When B sends back the response, ser would
relay it to A.
It
looks really simple, but I just can’t figure out how to do
it.
what
default config file you started with?
Apart of that when the user is not online, the default
config replies with 404 Not Found, the relaying between
phones when they are online is done there, being a
combination of calling function from registrar and tm
modules. So, if you start with the default config, no matter
is Kamailio or SER flavour, routing of the calls between
online users is provided there, just go through it in order
to understand better.
Cheers,
Daniel
