   NAT rebooting will cause probably tens of seconds or even minutes of
   network lossage anyways, so that will normally cause people to break
   the connection and try to reconnect before that. I think most of my
   friends will usually allow about 2-10 seconds of bad connection in gsm
   phone, before they will hang up and redial trying to fix the problem.
   Most of the NATs boot much slower than that.
   
=> here NAT rebooting includes NAT loosing its state and unfortunately
this kind of events is more frequent and fast.

   Another case of causing NAT mapping disappearing is the too long
   keepalive, but that should not really matter in VoIP traffic, as there
   is traffic going on fast enough to keep the NAT mappings up.

=> another case so there still are other cases...

PS: please don't forget that NAT traversal is explicitely outside
the WG charter.
