IVX 20
Function 232: Line disconnect
You can set the lines to detect the open loop interval (if available from the CO) and disconnect
more quickly. This will also allow the system to:
• Drop abandoned calls from Park and Hold.
• Reduce the opportunity for abandoned calls to be transferred by the auto attendant.
• Reduce the possibility that abandoned calls could create messages that are either silent or con-
tain CO-generated tones.
Since open loop intervals generated by the CO may vary in duration, use this function to program
IVX to less than or equal to the CO open loop interval.
If this programmed value is set unnecessarily low, IVX may falsely interpret static or a momentary
loop break as an open loop and disconnect a caller on hold or in the process of leaving a message.
If this value is set too high, IVX may not detect a valid open loop signal for fastest call processing.
Range: 1–255 (10–2,550 ms) (or 0 to turn off open loop detect off).
Default: 6 (60ms).
Function 24: Caller ID
This function activates the Caller ID capability in IVX — provided that the customer has ordered
Caller ID service from the telco. IVX will display the caller's name (or other designation such as
"
-
-
," etc.) for incoming calls or messages (or show the Caller ID number if the CO provides
OUT
OF
AREA
only a number).
Default: Disabled.
Esi-Dex and auto callback — This is accomplished by pressing REDIAL (during message playback) or
ESI-DEX (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 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 en-
tered:
• Local 7 — Local calls that can be dialed only as seven-digit numbers (IVX 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 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.
