Features
Any extension in the conference may add additional conferees to the
conference by repeating the above steps.
Conflict Dialing
Description
The system can differentiate between conflicting extension numbers such
as " 5 2345" and " 5 234" . This implies that extensions can be programmed
as I-, 2-, 3-, 4-, or 5-digit numbers with the first digits being identical.
The system selects the shorter extension number if the next digit is not
dialed within a preselected time.
A conflict exists between two extension numbers if the first number is
contained in the second number, starting with the first digit. For example,
1234 conflicts with 12345 but 1234 does not conflict with 123 (123 conflicts
with 1234).
Conditions
The following conditions apply to this feature:
.
.
_
.
.
First digit conflict between the access codes assigned to Executive
Busy Override and the Callback - Busy features, and other numbers
within the numbering plan, are permitted.
Feature Access Codes are not permitted to conflict with any other ac-
cess codes in the system.
Extension numbers may not conflict with Feature Access Codes.
ARS leading digit strings are not permitted to conflict with any other
access codes in the system. Extension numbers may conflict with ARS
leading digits.
Modem Pool Hunt group access codes cannot conflict with any other
access code in the system and no access code may conflict with a
Modem Pool Hunt group access code.
Conflict dialing applies to features that need to have access codes en-
tered (call forwarding for example). This includes the programming
features on the SUPERSETtelephones.
Normal system inter-digit timeout is
15
seconds (not ARS dialing). If a
conflict exists, the Dialing Conflict Timer applies.
Programming
Select an appropriate time--out period for System Option 50 (39 in Gener-
ic 1001) (Dialing Conflict Timer 2-l 0 s).
Operation
None.
