[reSIProcate] Network Down notification

[Amit Rastogi]

Thanks for the reply.
I tried and i am getting a 503 on TCP as well as UDP. i am using resip build
4631.
Reason i was thinking of re-registering etc.. was because i would like to
notify UA GUI of network disconnect so that it can reset itself ( call
control buttons/ display text ) etc....
 I also saw that UA comes back once the network connection is up.
 Now, i am thinking of sending options request periodically and check the
response to detect network down event. is it allright or do you suggest
something better?
 thanks again
