Programming Operations Guide
Incoming and outgoing call display
If you subscribe to Call Display services from your local telephone company, one line of
information about an external caller appears on the display after you answer a call. If you answer
before the Call Display information appears on your display, press
FEATURE 811 to view the
line number or line name. When you transfer an external call to another telephone in your system,
the same information appears on the recipient telephone display.
Depending on the services you subscribe to, incoming Call Display information can contain up to
three parts:
• the name of the caller
• the number of the caller
• the name of the line in your system that the call is on
Call display information can also be sent out when a system telephone calls out of the system.
What displays at the called party’s telephone, depends on what the private or public lines allow.
Outgoing call display information can be allowed or blocked at the system level or single
telephone level.
For each telephone, you can determine which information appears on the display first.
Note: If you transfer a call to a UK analog telephone (BCM 3.7), the CLID of the
originating call will not display on the analog telephone if the call is transferred after the
second ring. If the call is transferred before the second ring, the originating CLID displays.
Programming :
• Lines: Determine which telephones display incoming CLID for an analog line or that
provides CLID (GASM module), or for a target line:
“Determining line
assignments” on page 409 . (Caller ID set)
• Lines: Determine which PRI or BRI modules will allow outgoing CLID:
“Configuring the trunk module to line type” on page 143 . (Send name display)
• Loops: Determine which BRI modules will allow outgoing CLID (QSIG trunks,
only):
“Identifying BRI T-loops (ETSI, QSIG)” on page 282 . (Send name display)
• VoIP trunks: Determine which VoIP trunks will allow outgoing CLID (Services,
Telephony Services, General settings, IP trunking). (Send name display)
• Incoming call display, alpha tagging: Program a name to appear as call display when
a call comes in on an analog line that supports number-only CLID, or on target lines.
Refer to
“Using alpha tagging for name display” on page 463 .
• System: Determine whether name, line number, or system number appears first on
the telephone display:
“Configuring telco features” on page 456 .
