Dialing Table.

Log, Incoming
3. Automatic Caller ID Number Modification
When a call is received, the PBX can automatically modify the caller’s telephone number according to a
preprogrammed set of rules (Caller ID Modification Table). This modified number will be automatically
stored in
the extension’s Incoming Call Log, allowing the extension user to make a call to this number later
without worrying about CO Line Access numbers, area codes, etc.
Each trunk group can be assigned a modification table. Each table has ten formulas for modifying local/
international numbers, and one formula for modifying long distance numbers. When a call is received, the
PBX compares the received telephone number to the area codes programmed under "Local/International
Call Data" first. If a match is not found, the telephone number will be modified according to the method
programmed under "Long Distance Code".
