Navigation: System Settings > Line > T1 ISDN Call by Call

This tab is shown when the line Provider is set to AT&T. Settings in this tab are only used when calls are routed via a channel which has its Service set to Call by Call.

It allows short codes to be created to route calls to a different services according to the number dialed. Call By Call reduces the costs and maximizes the use of facilities. Call By Call chooses the optimal service for a particular call by including the Bearer capability in the routing decision. This is particularly useful when there are limited resources.

These settings must be edited offline. To enter offline editing, select Menu Bar Current User Icon > Offline Mode.
