Hi,
Please help! I am trying to do call forwarding when user not online. But I
run the route below, the call went through for the PSTN gateway but I can
see multiple request. Anyone knoe what is happening ...thanks.!!
route{
# 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") {
save("location");
break;
};
};
lookup("aliases");
if (uri=~"sip:1234[0-9]+@iptel.org") {
rewritehostport("1.2.3.4:5060");
# first dump the message to a file using cat command
exec_msg("printenv SRCIP > /tmp/exectest.txt; cat >>
/tmp/exectest.txt");
# and then rewrite URI using external utility
# note that the last echo command trashes input parameter
if (exec_dset("echo $SIP_RURI ;echo SIP_SRCIP ;echo>/dev/null")) {
sl_send_reply("300", "Redirect");
} else {
sl_reply_error();
log(1, "alas, rewriting failed\n");
};
};
if (!uri==myself) {
t_relay();
break;
};
if (method=="INVITE") {
fix_nated_sdp("3");
append_hf("P-hint:Invite");
# native SIP destinations are handled using our USRLOC DB
if (!lookup("location")) {
sl_send_reply("", "Connecting");
break;
};
};
if (method=="ACK"){
sl_send_reply("", "ACK");
};
# 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();
break;
};
}
# all incoming replies for t_onrepli-ed transactions enter here
onreply_route[1] {
sdp_mangle_port("-12000");
if (isflagset(6) && status=~"2[0-9][0-9]"){
append_hf("First Route");
fix_nated_contact();
fix_nated_sdp("1");
force_rtp_proxy();
} else if (status=~"2[0-9][0-9]"){
if (uri=~"sip:019[0-9]+@iptel.org") {
append_hf("019");
fix_nated_contact();
fix_nated_sdp("3");
}
else{
append_hf("2nd Route");
fix_nated_contact();
fix_nated_sdp("2");
fix_nated_sdp("3");
