Reference Guide for the Model RT338 ISDN Router

Configuring Call Control

The Model RT338 router provides call control management functions for the remote node and
remote dial-in user. These functions are budget management, blacklist, and call history, which are
on the Call Control menu. Select option 9 from Menu 24 to display the Call Control menu.

Configuring the Blacklist

The blacklist function prevents the router from redialing an unreachable phone number (a number
to which it has been unable to connect). In Menu 24.9.2, the router maintains a list of phone
numbers (up to a maximum of 14) to which it does not make an outgoing call. When the router
attempts to dial a phone number and fails a certain number of times (configurable in Menu 24.9.1),
the phone number is put onto the blacklist. You must restore the number manually before it can be
dialed again. You can remove a phone number from the list by entering its index number at the
Remove Selection prompt.

Configuring Budget Management

Use the budget management functions to set a limit on ISDN utilization to prevent any accidental
overuse. This function limits the total outgoing call time of the router over a period of time to each
remote node and remote dial-in user (callback only). When the limit is reached, the call is dropped
and further outgoing calls to that remote node or remote dial-in user (callback) fail.
If the total outgoing call time exceeds the set limit, future outgoing calls are not made and the
current call is dropped. After each total period, the total budget is reset.
The default for the total budget is 0 minutes, and the total period is 0 hours. These values disable
budget control. You can reset the total outgoing call time in Menu 24.9.3 - Budget Management.
The total outgoing call timer can be programmed to reset itself periodically through Menus 11
and 13.
