make a dialing plan, e.g.
if USER == number { if user start with 0 { #PSTN call route to gateway } else { #IP call lookup("location") ... } }

Just a quick question....I am using numerics as the username (ex. 111000001) of my hosts. I am able to make pstn calls through my pstn gateway. My question is how do i configure the routing request lock to allow ip to ip calls between two hosts. if i dial 111000002 it routes the call to the pstn instead of to the other host.
here is my config so far.
# ------------------------- request routing logic ------------------- route{
# 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 record_route(); # loose-route processing if (loose_route()) { t_relay(); break; };
# is it a PSTN destination? (is username nummerical and does not begin with 8?)
if (uri=~"^sip:[0-79][0-9]*@") { # ... forward to gateways then; # check first to which PSTN destination the requests goes; # if it is US (prefix "1"), use the gateway 64.72.107.2... if (uri=~"^sip:1") { forward(64.72.107.2, 5060); } if (uri=~"^sip:011") { forward(64.72.107.2, 5060);
} else { if (!lookup("location")) { sl_send_reply("404", "User Not Found"); log("SER: Dest User Not in location table.\n"); break; }; if (!t_relay()) { sl_reply_error(); }; break; }; }
# if the request is for other domain use UsrLoc # (in case, it does not work, use the following command # with proper names and addresses in it) if (uri==myself) {
if (method=="REGISTER") {# Uncomment this if you want to use digest authentication if (!www_authorize("sipua.cytelcom.com", "subscriber")) { www_challenge("sipua.cytelcom.com", "0"); break; }; save("location"); break; };
# native SIP destinations are handled using our USRLOC DB if (!lookup("location")) { sl_send_reply("404", "Not Found"); break; };}; # forward to current uri now; use stateful forwarding; that # works reliably even if we forward from TCP to UDP if (!t_relay()) { sl_reply_error(); };
}
