Function 24: Caller ID
This function activates the Caller ID capability in the IVX C-Class system — if the customer has
ordered Caller ID service from the Telco. The IVX C-Class system will display the caller’s name (or
“
OUT-OF-AREA,” etc.) for incoming calls or messages (or show the Caller ID number if the CO only
provides a number).
Default: Disabled.

and auto callback — This is accomplished by pressing FLASH/RDL or ESI-DEX either
during message playback or after an Esi-Dex search. Caller ID numbers received from the CO are 10
digits long (and include the area codes for local calls). In auto callback, the IVX C-Class system
assumes all calls are to be long-distance and will automatically add a “1” prefix to the 10 digits
to be dialed.
A table of local area codes can be programmed to indicate that calls to those area codes are to be
dialed as local calls. Select one of the following two types of local dialing for each area code entered:
• Local 7 — Local calls that can be dialed only as seven-digit numbers (the IVX C-Class system strips
the area code before dialing and will not add a “1” prefix).
• Local 10 — Local calls that can be dialed only as 10-digit numbers (the IVX C-Class system will not
add a “1” prefix).
For an area code that can be called as a long-distance number (with a “1” prefix) and as a local number
(10 digits without a prefix), decide which case is the more prevalent and then add to or exclude from the
area codes exception list accordingly. Thus, some of these calls must be made manually.
Note: Since the Caller ID information is transmitted from the CO during the silence between the first and
second rings, enabling this feature will delay the answer of inbound calls until the second ring
.
