Hi,
I already have a SIP proxy which handles SIP registers and acts as RTP proxy.
But that one does not handle presence messages as SUBSCRIBE and PUBLISH.
Is it possible to use Ser together with my Sip proxy ?
What I mean:
- SIP clients will send all messages to SER.
- SER will forward SIP messages like REGISTER, INVITE, NOTIFY to my SIP proxy with no
modification to the message.
- SER will also handle SIP messages related to presence and resource lists.
Is this possible ?
What kind of configuration is needed ?
Thanks,
ilker

Hi,
your solution is possible - separated presence server from other SIP
communication. For forwarding you need cfg like this:
if (method=="...") { # here put method name which should be forwarded
if (!t_newtran()) {
log(1, "newtran error\n");
sl_reply_error();
break;
};
if (!t_forward_nonack("machine.domain.com", 5060)) {
log(1, "forward failed\n");
t_reply("500", "Forward failed");
}
break;
}
I'm using SER as proxy and other SER as presence server. Proxy forwards
presence related messages to presence server, it looks like:
route {
# XML RPC
if (method == "POST" || method == "GET") {
create_via();
dispatch_rpc();
break;
}
# initial sanity checks -- messages with
# max_forwards==0, or excessively long requests
if (!mf_process_maxfwd_header("10")) {
sl_send_reply("483","Too Many Hops");
break;
};
if (msg:len >= max_len ) {
sl_send_reply("513", "Message too big");
break;
};
# we record-route all messages -- to make sure that
# subsequent messages will go through our proxy; that's
# particularly good if upstream and downstream entities
# use different transport protocol
if (!method=="REGISTER") record_route();
# subsequent messages withing a dialog should take the
# path determined by record-routing
if (loose_route()) {
# mark routing logic in request
append_hf("P-hint: rr-enforced\r\n");
route(1);
break;
};
if (uri==myself) {
if (method=="REGISTER") {
if (!www_authenticate("test-domain.com", "credentials")) {
www_challenge("test-domain.com", "0");
break;
};
save("location");
break;
};
# ... process other messages here ...
if ((method=="SUBSCRIBE") || (method=="PUBLISH")) {
log(1, "Forwarding request\n");
if (!t_newtran()) {
log(1, "newtran error\n");
sl_reply_error();
break;
};
if (!t_forward_nonack("presence-server.mydomain.com", "5060")) {
log(1, "Forward to PS failed\n");
t_reply("500", "Forward failed");
}
break;
};
# native SIP destinations are handled using our USRLOC DB
if (!lookup("location")) {
sl_send_reply("404", "Not Found");
break;
};
}
route(1);
}
route[1]
{
# send it out now; use stateful forwarding as it works reliably
# even for UDP2TCP
if (!t_relay()) {
sl_reply_error();
};
}
