Hi-
I am having a problem where if I parallel fork a call, my failure_route gets
called after the caller hangs up. I thought adding t_check_status("487") to
the failure_route would take care of that, but it still t_relays when I
don't want it to. This only seems to be a problem if it parallel forks and
one of the SIP targets is not available. If I dial an alias with a single
[not forked] target the t_check_status("487") works fine.
Here is my code.. any thoughts?
Thanks much.
