Do not take my explanation as a "no" - I just wanted to point the
obstacles ; and work around the statefull part may be encoding some
user/contact ID in the callid or from tag, so when you receive back the
reply, you do not need a transaction to find out the corresponding
contact you pinged - you can simply extract the contact from the
reply.....just an idea.

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....

Hi All,
The 1.9 has an awesome event interface and I really appreciate
the great work by the developers. I was looking at an option to
raise an event when a registered user becomes unreachable.
Say, for eg: I use keep-alive method as OPTIONS in the
nat_traversal module and if I do not get a response from any UA,
is it possible that opensips can raise an event for the same. Is
it somehow possible from the script, or additional work on the
code will be required.
I think, this feature might be useful in many ways !!
Thanks for any pointers.
