indeed, to make everybody happy,
the solution is provided by

This is an old problem - often called
registration hijacking.
Some call it a feature: 3rd party registration ;-)
/Christian
After authentication, use check_to() for REGISTER and check_from()
for all other SIP requests.

I have a security matter with my configuration (default one), it's
possible to register using login/password and to set anything in the
contact field.
So if you have an account 106/password, it's possible to be 105 in
the location database!
How is it possible to deny that kind of matter..? Thanks
Is it useful to use: method_filtering of the REGISTRAR module
Or is it better to so something whith the values below and a compare
function??
$ct - reference to body of contact header
$ar - realm from Authorization or Proxy-Authorization header
$au - username from Authorization or Proxy-Authorization header
if ($ct != $au@$ar) {
sl_send_reply("403", "User and login must be the same");
};
Best Regards,
