Maybe you got to get some traces with sip set debug on on asterisk or ngrep
in kamailio to check whereis the problem.
I think you are not authenticating correctly
Check if you insert on sipusers and sipppers table what is commented on KB
by asipto.
Maybe your Kamailio is not responding to OPTIONS (qualify=yes)
add at the beginning of your kamailio.cfg file
request_route {
if(is_method("OPTIONS") ) {
sl_send_reply("200","Keepalive");
exit;
}
.....
To solve qualify problem
