[OpenSIPS-Users] raise event when a registered user is unreachable

[Bogdan-Andrei Iancu]

Hi Jayesh,

Firing an event is not a problem - the problem is in NAT pinging, there 
is no state for the tractions. Basically the modules doing NAT do not 
care of the replies (as for pining is not relevant), so you do not know 
which ping and for what contact it failed, in order to trigger the event.

Switching to statefull pinging may be expensive from resources point of 
view....
