3.1 Incoming Call Features
3.1.1 Calling Line Identification (CLI) Distribution & Call Block
Description
Directs an incoming Trunk line call to a preprogrammed destination when the caller's identification number
(e.g., Caller ID) matches the number in the System Speed Dialing Table that is used as the Caller ID Table.
Each Caller ID number (telephone number for each System Speed Dialing number) can have its own
destination.
If an incoming call does not notify a Caller ID, it is possible to refuse reception (Call Block).
Caller ID Modification
Received Caller ID is modified in the following steps:
1. Caller ID Modification by Length of Digits
Pre-programmed numbers (max. 6 digits) can be added to the front of the Caller ID if the Call ID of
digits received from the network is within the range below:
• International: 12 digits or more (default)
• National: 8 digits (default) to 11 digits (1 value removed from International)
[Example]
• Minimum Caller ID Digits (International): 12
• Added Number (International): 001
Before modification: 81-50-1234-5678
↓
After modification: 00181-50-1234-5678 (Add "001")
2. Caller ID Modification by leading numbers
After the Caller ID is modified by the Length of Digits, the PBX checks the leading numbers of the
modified number for an area code programmed in Caller ID Modify Table in Web Maintenance
Console. If it finds such a code, it removes digits and adds a number to the modified number.
[Example]
• Area Code: 00181
• Removed Number of Digits: 5
• Added Number: 0
Before modification: 00181-50-1234-5678
↓
After modification (1): 50-1234-5678 (remove "00181")
↓
After modification (2): 050-1234-5678 (Add "0")
3. Adding the Idle Line Access (Local Access) number
After the Caller ID is modified by the leading numbers, the Idle Line Access number (Idle Line Access
(Local Access) - 1) is added to the modified number. (Refer to 2.1.1 Feature Number Lists for User)
[Example]
• Idle Line Access (Local Access) number: 9
