Function 2: CO lines IVX 128
E.12
Function 24: Caller ID
This function activates the Caller ID capability in IVX 128 —
provided that
the customer has ordered
Caller ID service the Telco. IVX 128 will display the caller’s name (or other designation such as “
OUT
-
OF
-
AREA
,” etc.) for incoming calls or messages (or show the Caller ID number if the CO only provides
a number).
Default:
Disabled.
Esi-Dex and auto callback
— This is accomplished by pressing
REDIAL
or the
Esi-Dex
key 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, IVX 128 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 (IVX 128 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 (IVX 128 will
not
add a
“1” prefix).
If you have 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), you must decide which case is the more prevalent and
then add to or exclude from the area codes exception list accordingly. Therefore, some of these
calls will have to be made manually.
Note:
Since the Caller ID information is transmitted from the CO during the silence between the
first and second ring, enabling this feature will delay the answer of inbound calls until the
second ring.
