[Serusers] Configure Incoming in SER

[Andrey Kuprianov]

yes! sure :)

Suppose prefix of SER-B is 123 and the rest of URI is some number
(e.g. sip:1235555 at blah-blah.net ), then in your INVITE route:

.....

sl_send_reply("100", "Trying");

# Check if From SIP URI is not from our domain, but has prefix 123
if (!check_from() && !search("^From:*sip:123[0-9]*@") ) {
   if (!www_authorize("","subscriber")) {
       www_challenge("","1");
       break;
   };
};

.....

This is too simple regular expression for search() function, i think
you'll need more complicated than this. :(Im afraid this one might
match not just 123 prefix but anything else... Try this anyway. See if
that works.
