yes, signaling based events (like a rejection or timeout from the user)
may be considered a good reason to delete his registration.
Now, on Transport related error from OpenSIPS itself:
UDP - there is no way to get the potential ICMP errors :(
TCP - the t_relay() function do return with error if it failed to
put the message on the network. We need to work out some specific return
code to indicate a net err.
Let me add these 2 things on the TODO list for 1.10 - removing contacts
and NET indication from t_relay .
