If I understood well, when each call is made u give him duration time 
based on the billing.
Its wrong direction at start. The only possible solution is in the 
asterisk. You need global variable with total time for all channels, 
then you need the timer.
Timer can be one by each channel, and each channel timer decrements same 
global time variable when it becomes a zero or less terminate all active 
channels for that account.

The other way would be to have one timer who decrements global time 
variable based on number of active channels. Timer is inactive when 
there is no active channels for account.
To explain this, if timer decrement cycle is  n second  then  he should 
decrement global remained time variable  ACCOUNT_TIME = ACCOUNT_TIME- (n 
active channels at the moment) x (timer cycle in seconds).
Then check condition ACCOUNT_TIME <= 0 if true hangup all active 
channels for that account.
Then check condition (n active channels for account == 0) if true stop 
the timer.
The "n active channels" should be checked on asterisk.

If you create account time variable when first channel of account 
becomes active  like AV_{some id} and timer who will process this 
remaining time.
Then on each new channel for that account you just increment other 
variable NAC_{some id} or decrement.
The best is that this variables be asterisk variables (global).

We have not tried above, so be my guest if you have free time :)
