The details of detecting a loss of network connectivity vary from OS  
to OS.
Therefore, it is not currently implemented in reSIProcate. You could  
notice that your requests timeout. (local 408) for UDP and get 503s  
on TCP. Beyond that, we'd have to implement something specific to the  
OS or use some keep-alive mechanism.

NOTE: You don't have to 'unregister' and if you don't move (and are  
using UDP) you don't have to re-REGISTER either.
