Call Control
The Prestige provides two Call Control Management functions for the
Remote Node and Remote Dial-in User. They are the Budget
Management and Blacklist. The Budget Management function provides
the budget control for the outgoing call and a way for users to set a limit
on their ISDN utilization to prevent any accidental usage. It limits the
total outgoing call time of the Prestige over a period of time for each
Remote Node & Remote Dial-in User (callback only). If the total
outgoing call time exceeds the set limit, future outgoing calls will not be
made and the current call will be dropped.
The Blacklist function prevents the Prestige from re-dialing to an
unreachable phone number. It is a list of phone numbers, up to a
maximum of 14, to which the Prestige will not make an outgoing call. If
the Prestige tries to dial to a phone number and fails a certain number
(configurable in the menu 24.9.1) times, then the phone number will be
put onto the blacklist. The user has to enable the number manually again
to be dialed.
