[Asterisk-Users] ASTCC: How to reset periodically all "card in use" flag back?

[Ronald Wiplinger]

If a user calls and hangs up before the destination party rings, than 
the in-use flag remains set! This is one case, but maybe there are many 
other cases.
I have created a number the user can dial to reset this flag. However, 
that is written in the manual!!! Who reads a manual anyway!!!!

I want to make to reset all in use flag with a program. Has anybody done 
it, or has a better idea?
My idea is to check every 5 minutes, the database, which cards are set 
in use and check if this is true, if not reset it.

Q: How do I know if a card is in use?
