Function 24: Caller ID
This function activates the Caller ID capability in the ESI-50L — if the customer has ordered Caller ID service
from the Telco. The ESI-50L 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.
Esi-Dex and auto callback
1
— This is accomplished by pressing REDIAL 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 ESI-50L 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 ESI-50L 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 ESI-50L 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.
