About credit limit

As the attendant, you can control credit limit on a per-station basis to regulate calling privileges for cash-paying customers. Your facility can choose from three versions of the credit limit feature as follows:

Trunk disconnect

Trunk disconnect limits calls from a

 

 

 

credit-limit station to a certain

 

 

 

duration. Calls that exceed the

 

 

 

duration are automatically

 

 

 

disconnected. This method is

 

 

 

intended for highly restrictive

 

 

 

environments (e.g. prisons or

 

 

 

businesses that limit usage on certain

 

 

 

phones).

 

 

 

 

 

 

Lookahead credit

The lookahead option pre-calculates

 

 

 

a charge and corresponding

 

 

 

maximum call duration for each call

 

 

 

type. Calls are automatically

 

 

 

disconnected when the current credit

 

 

 

value is exhausted. A warning tone is

 

 

 

sent to the caller 60 seconds before a

 

 

 

call is disconnected.

 

 

 

 

 

 

Positive value

The positive value credit limit never

 

 

 

disconnects a call in progress.

 

 

 

However, the station is not allowed

 

 

 

to begin the call, unless the credit

 

 

 

value is above zero.
