This is looking bad!
Here's the next problem then, calls to other extns in the group would need to do the same thing.
Calls to 1001 if unanswered would ring to 1000 then 1002 then 1003 then VM
Calls to 1002 if unanswered would ring to 1000 then 1001 then 1003 then VM
If we forget about VM is it possible to re-route to a HG?
So I could setup multiple HG and re-route to those if the customer agrees to bin the VM at the end?
