Hello,
What you can do is send the call to a destination which is not available
at all, control the amount of time you want to give the client to
register via the fr_timer, and when that timeout is exceeded try to
route the call to the client.
Short snippet of code would be
if (!t_relay("3"))
{
if((is_method("INVITE")))
{
exec_avp("some script to wake-up the client");
# relay to localhost, discart port
$du = "sip:127.0.0.1:9";
# wait two seconds for the client to register
$T_fr_timeout = 2;
t_on_failure("route_to_client");
t_relay();
exit;
}
}
failure_route[route_to_client] {
if (t_was_cancelled())
exit;
# after two seconds, this will get called
# see if the client is registered now
lookup("location");
t_relay();
exit;
}

Hello Guys,
could you give the last clue on this? The point is once the UA is
re-registered, how to forward the call to it?
Thanks,
Leo
