  Jon Bonilla (Manwe) pointed out on the -dev list:
  "I guess that having only ip-phones in mind is not a good approach. Since it is
  possible to have a sip proxy connected to asterisk we could receive a 407
  (unauthorized) or 483 (too many hops) as response and dialog ending would not be
  a good behavior."
  So modified.
