  Disables auth_options_request option by default.
  
  The auth_options_request option was created to do authentication
  on OPTIONS request just like INVITES are done.  Since it has been
  noted that some endpoints use OPTIONS requests as a way of qualifying
  a peer and that a 401 authentication response could result in
  interoperability issues, this option has been disabled by default.
