Balance and Credit Limit

In addition to Tariffs, each Customer or Account has two basic Rating and Billing parameters associated with it; they are, Balance and Credit Limit. A negative Balance represents the amount of money an Account or Customer owes the upper level Customer to which it is a Customer or Account.  A positive balance represents the amount the already paid by the Account or Customer.  

With each successful call, the Balance is reduced by amount equal to the price of the call.  The Credit Limit set is the maximum negative value the Balance can reach.  Once the Balance has reached the Credit Limit, an Account or Customer will be blocked and will not be allowed to make more calls.

Balances can be increased via online payment, top-up voucher or by manual maintenance performed by the upper level Customer.
