1.16 Caller ID Features

1.16.1 Caller ID

Description

The PBX can receive Caller ID information (a caller's name and telephone number) from calls received on CO lines. This information can be shown on a proprietary telephone (PT) display when receiving a call and can be used to direct calls from specific callers to specific destinations automatically. Additionally, Caller ID information is logged in the Incoming Call Log of the extension which received the call, allowing the caller to view a record of incoming calls or make a call to a person in the call log later. The PBX can be programmed to modify a caller's telephone number when it is received and, for example, add a CO Line Access number or add/delete certain digits of incoming telephone numbers automatically. This allows an extension user to be able to make a call later to a telephone number logged in his or her call log without worrying about CO Line Access numbers, area codes, etc.

Notes • The term "Caller ID" used in this Feature Guide refers to features that can receive caller information sent from the telephone company and received on analog, ISDN, and T1 lines. Your network provider may use a different name for this type of service. • To receive Caller ID information, you must subscribe to the telephone company's Caller ID service and enable Caller ID for the appropriate CO line through system programming.

1.	Caller ID Features
	There are three features which can receive Caller ID information. The available feature depends on the type of CO line receiving the call. Feature Description Details in Caller ID Receives caller information sent from the telephone company over analog CO lines. — Calling Line Identification Presentation (CLIP)   Receives caller information sent from the telephone company over ISDN lines. — Automatic Number Identification (ANI)   Receives caller information sent from the telephone company over T1 lines. • 1.20.1 T1 Line Service
2.	Caller ID-Related Features
	Features Description Details in Calling Line Identification (CLI) Distribution Caller ID information received by the PBX is used to direct calls from specific callers to specific destinations. The caller's telephone number and a destination must be assigned in the System Speed Dialing Table. • 1.1.1.4 Calling Line Identification (CLI) Distribution Incoming Call Log Caller information is automatically recorded in the call log of the extension which received the call. This information can be used to view a record of incoming calls or make calls to any number in the call log. • 1.16.2 Incoming Call Log
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 CO line 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". [Programming Example: Caller ID Modification] Note When Caller ID information is received from a call on an ISDN line and the call type is International, National, or Subscriber, the following modification table is used instead of the above table: Data entered under "Removed No. of Digits" and "Added No." for International, National, and Subscriber call data will be applied respectively to international, long distance, and local calls. <Modification Flowchart>
4.	System Speed Dialing Table
	The System Speed Dialing Table can store telephone numbers, names, and CLI destinations for hundreds of callers. a) Telephone Number: Contains a CO Line Access number and the caller's telephone number. If Automatic Caller ID Number Modification is used, telephone numbers should be stored in the System Speed Dialing Table in their modified format in order for CLI distribution to function. b) Caller's Name: Shown on the display and logged (Incoming Call Log, Station Message Detail Recording [SMDR]) when a call from this telephone number is received. c) CLI Destination: The destination to which an incoming call from the stored telephone number is directed via the CLI distribution feature. [Programming Example: System Speed Dialing Table] *1 System Speed Dialing Name [002] *2 System Speed Dialing Number [001]
5.	Displaying the Caller's Name
	In addition to the System Speed Dialing Table, each extension can store names and numbers in Personal Speed Dialing. Therefore, it is entirely possible for the same telephone number to be stored under a different name in different locations within the PBX. When a call containing Caller ID information is received, the PBX will search for the caller's name in the following order, then show that name on the display and log it via SMDR. 1) Personal Speed Dialing data of the extension which received the call 2) System Speed Dialing Table 3) The Caller ID information received from the telephone company
	If a caller's name is not stored in the PBX or sent from the telephone company, it will not be displayed or logged.

Conditions

•	Caller ID signaling type can be selected through system programming ( Caller ID Signal Type [490]).

1.16.2 Incoming Call Log

Description

When a call containing Caller ID information is received by an extension, the information is shown on the telephone display, notifying the extension user of the caller's identity. This information is also automatically logged in the Incoming Call Log of the extension, and can be viewed later or used to call that caller back. Each extension and incoming call distribution (ICD) group has its own Incoming Call Log.

Call Log button

The Call Log button will alert an extension user to any missed (unanswered) calls. A flexible button can be customized as the Call Log button, and will indicate the status of the Incoming Call Log for the extension or corresponding ICD group, as shown below.

Light pattern Status of the corresponding call log Red on There are call records in the log which have not been viewed. Off There are no new call records in the log.

Conditions

•	If the answering destination is not the original destination (Call Forwarding (FWD)–No Answer and Call Pickup): If a call is not answered and forwarded to another destination, or if an extension picks up a call ringing at another extension, the call is logged in the Incoming Call Logs of both the original and the answering destination.
•	Incoming Call Log for Calls to an ICD Group If a call directed to an ICD group is not answered, the call is logged in the Incoming Call Log of the ICD group. If the call is answered, it is logged in the call log of the answering extension only.
•	Incoming Call Log for Calls to a PS Each portable station (PS) also has an Incoming Call Log. When a call is directed to a PS, the call will be logged in the call log of the PS even when:
	a) The PS is out of range. b) The PS is turned off. c) The Cell Station (CS) is busy.
•	Incoming Call Log Display Lock The Incoming Call Log of an extension can be locked through personal programming (Directory and Call Log Lock) to prevent other users from viewing its contents. If locked, the Outgoing Call Log and Personal Speed Dialing are also locked. An extension personal identification number (PIN) is required to use this feature. ( 1.24.1 Extension Personal Identification Number (PIN))
•	Incoming Call Log Memory The total number of incoming calls that can be logged by the PBX is limited. ( 5.1.1 Capacity of System Resources) The maximum number of calls that can be logged in the Incoming Call Log of each extension and ICD group can be specified through system programming. When a call log is full, the oldest call will be replaced each time a call is received.
•	Automatic Caller ID Number Modification If the PBX is programmed to automatically modify incoming telephone numbers, the modified numbers will be logged in the Incoming Call Log.
