[asterisk-users] Pre-paid Billing

[Alex Balashov]

You need some outside process to keep call state, probably using the 
Manager API and/or AGI.  The outside process can listen to periodic call 
setup events at a relatively low polling interval and make appropriate 
adjustments to the user's credit in the database, which will then allow 
you to determine whether to allow another call to be set up given the 
available credit, etc. to a relatively high degree of accuracy.
