3.Leading Number Table 3 Assignment
Store the area codes and/or telephone numbers as leading number that will be routed by the ARS feature. In this table, the Routing Plan (refer to "4. Routing Plan Table 4 Assignment") is selected for each number.
The additional (remain) number of digits must be assigned only when "#", for example, is needed after a dialled number. The "#" is added after the assigned number of digits of dialled number (excluding a leading number).

If a dialled number matches a leading number, the number will be modified according to the corresponding Routing Plan Table and the modified number will be sent to the trunk when the assigned additional (remain) number of digits are dialled.
If a dialled number matches multiple leading number entries, the leading number entry with the lowest numbered location will have priority.
