Hi Satish,
The scripting you use is authenticating only INVITEs (actually all
requests) coming from your own users (based on the SIP domain in From
header). IF the caller is not a local user, the call is accepted only if
callee is a local user (based on the SIP domain in the RURI).
If you simply want to decline any calls from non-local callers, on the
"else" branch of the "if(is_from_loca())" reject the call:
send_reply("403","Forbidden");
exit;
Best regards,

I have question about how to stop INVITE coming from unknown source or
not subscribed user.
I have opensips front end proxy and Freeswitch PSTN
But recently i have seeing some calls coming from unknown source and
method is INVITE so it is sending direct INVITE to opensips and
opensips forwarding them to Freeswitch, How do i tell opensip if
INVITE from non-registered user then drop it.
As you see in Freeswitch section, if you see INVITE forward it to
Freeswitch, How do i check INVITE is authenticated or not?
This is what i have in cfg.
....
....
if (is_from_local())
{
# authenticate if from local subscriber
# authenticate all initial non-REGISTER
request that pretend to be
# generated by local subscriber (domain from
FROM URI is local)
if (!check_source_address("2")) {
if (!proxy_authorize("", "subscriber")) {
proxy_challenge("", "0");
exit;
}
consume_credentials();
# caller authenticated
}
} else {
# if caller is not local, then called number
must be local
if (!is_uri_host_local()) {
send_reply("403","Rely forbidden");
exit;
}
}
}
# To FreeSWITCH
if (is_method("INVITE")) {
if ( uri=~"^sip:[1-9][0-9]{10,15}@.*") {
xlog("Sending call to ===> Freeswitch\n");
route("to_dispatcher");
exit;
};
}
