[asterisk-users] Dial() after the h extension has been invoked?

I have a setup which comprises some "front-end" Asterisk servers which have
SIP trunks to external providers, and very simple dial plans, and some "back-
end" servers which only talk to the front-end machines, and have the majority
of my dialplan logic on them.
I use Dial() commands with custom SIP headers to pass information (eg: about
the current state of a call) between the front-end and back-end machines, and
this works very well.
However, I can't use a Dial() command in the h extension to notify the other
machines that a call has ended and they can now delete their state information
about that call. If I try to, I get the error:
app_dial.c:2245 in dial_exec_full: Caller hung up before dial.
I guess i can see why Asterisk complains about being asked to Dial() after the
inbound call leg has ended, but in this case I have a reason for doing so.
Can anyone suggest how I might be able to do this? I need to perform a Dial()
command after an inbound channel has hung up. I do not expect the Dial() to
bridge to anything (the context being dialled simply does some database
manipulation and then hangs up without even bothering to answer).
Any suggestions welcome :)

The remaining 1% might be something else, but check the routing anyway.
