Hello,

do you want to check if caller (origin) is registered or if callee (destination) is registered? Like one can call to pstn only if has a phone registered for itself?

Or you want to say that you want to forward to gateway only for registered users. But maybe you want for local subscribers.

Cheers, Daniel

Hi.

I try to use Kamailio 4.1 git version as registrar and PSTN gw.

Need accept register from users. Its OK, I made it and use save() function - from keep registrations in case of kamailio restart.

Need forward calls to gw, but only for registered users. If I understand correctly in INVITE enough check registered("location"), isnt it? but it's not work, i need verify auth again.

Routing part of my config:

route { # initial sanity checks - skip in letter

# We are registrar!

     if (is_method("REGISTER"))
     {
             sl_send_reply("100", "Trying"); # send "Trying, dont threat on me
             if(isflagset(FLT_NATS))
             {
                   setbflag(FLB_NATB);
                     # uncomment next line to do SIP NAT pinging
                     ## setbflag(FLB_NATSIPPING);
             }

             # we must check auth right now
             # WORK: if (!www_authorize("$fd", "subscriber"))
             if (!auth_check("$fd", "subscriber", "1"))
             {
                 # WORK: www_challenge("$fd", "0");
                 auth_challenge("$fd", "0");
                 # send me requisites plz
                 exit;
             } else
             {
                 # ok. auth accepted, save in location
                 if (save("location"))
                 #if (save("location","0x04","$fd"))
            {
                     xlog("L_WARN", "Save OK in location sip:$au@$fd");
            } else
            {
                     xlog("L_WARN", "Save FAIL in location sip:$au@$fd");
            }
             }

### THAT FUNCTIONS ALWAYS WRITE IN LOGS # "!registered" "!lookup" for both registered and unregged users

             # number change - FIX late
             # check may be used dialplan automatically?
