  INVITE 403 Forbidden response always retransmits the maximum times.

  Asterisk sends a 403 Forbidden response if authentication fails for an
  INVITE as required.  However, it ignores the ACK and keeps retransmitting
  the response.

  * Made not delete the to-tag in the dialog so the expected ACK can be
  matched with the dialog and stop the retransmissions.
