This tab is shown when the line Provider is set to AT&T. This table is used to set additional fields in the NSF information element after initial number parsing by the TNS tab. These are used to indicate the services required by the call. If the channel is set to Call by Call, then further parsing is done using the records in the Call by Call tab.

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