Yes, this is a issue that needs to be considered. Also each call might
be on a different cost per minute depending on the number called e.g. in
the UK geographic calls are costed lower then mobile calls.

The only solution I can think of at the moment is to write a daemon that
uses the manager interface to hold all calls in memory and manages the
current call credit available at the current time per account. If the
credit expires for that account it hangs up all channels for that
account. The only problem at the moment is I can't figure away to
dynamically play a warning to the callers.
