You will need to keep track of the call duration for each channel in a 
persistent store -- something like MySQL.

You may also want to read up on setting the absolute timeout on a channel 
so a caller won't consume all of your 'prepaid' (nothing is free) minutes 
and drive you into unexpected charges.
