Direct Inward Dialing Call Forward No Answer Timer

Call Forward No Answer takes precedence over the Message Center
feature.

Electronic Lock Network Wide/Electronic Lock on Private Lines

For Call Forwarding, the COS and NCOS used for the forwarding call can be
taken from either the forwarding telephone or from the forwarded telephone,
depending on the option defined in the Customer Data Block.
For example, telephone B call forwards all calls to an external trunk.
Telephone A calls telephone B. If OPT = CFF in LD 15 (Call Forward
forwarded to party’s COS and NCOS), the COS and NCOS of telephone B
are used for forwarding the call to the trunk. If OPT = CFO (Call Forward
originating party’s COS and NCOS), the COS and NCOS of telephone A
are used for forwarding the call to the trunk.
Group Call
Group Call cannot be applied to Call Forward No Answer.
Group Hunt
Call Forward No Answer (CFNA) can optionally be configured to use a Pilot
DN. This option is available when the HUNT DN or the FDN is defined as
a Pilot DN.
If an idle station attempted for termination has CFNA defined, then the
station is rung. If the station does not answer within the customer specified
number of ring cycles, then group hunting will continue with the next DN
in the group. The calling party will continue to hear ring back tone until
one of the termination conditions mentioned in the "Group Hunt" feature
description (the last condition is not applicable in this case) is met, or until
they releases the call.
Group Hunting Queuing Limitation Enhancement
An external call is made to the PLDN. An idle group hunt list member
station is rung but does not answer. If the member station has Call Forward
No Answer (FNA) or Call Forward by Call Type Allowed (CFTA) Class of
Service, then the call is transferred to the attendant after the number of ring
cycles defined for Call Forward No Answer has been reached. If the call
is an internal call, then the system searches for another idle group hunt
list member.
Hot Line
Any Hot Line telephone can be assigned Call Forward No Answer but it
applies only to the two-way Hot Line capability.
