Definition
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.
