[Asterisk-Users] ASTCC - card in use

[Ronald Wiplinger]

Is there a solution for the problem that the card in use flag is set, 
after the user hang up?

The flag remains set, if the user hang up, after the price for the call 
will be announced.
It is bad (for the business), because this happens most of the time only 
for NEW users!

Solutions?
1. Do we need the flag at all, if we use the phone number as card number 
anyway? If we can use the phone number as card number, we could omit it. 
However, I plan that I will have other premium features, where I need to 
punch in a card number!!!
2. Could we use a extension number to reset the flag?
3. Could we use a cron job to reset the flag, if the extension number is 
not in a call? This one sounds for me most reliable, but at the moment 
the most complicated one to figure it out by the cron job and reset it 
from there.

Is a solution available?

bye
