Call Forward No Answer
When Call Redirection by Day (CRDAY) is activated, calls unanswered
after a specified number of rings are sent to Call Forward No Answer
feature (CFNA) and forwarded to the alternate DN based on the alternative
days/holidays configured for the set.
Call Forward All Calls
All unanswered incoming calls are sent to the Call Forward All Calls feature
if there is no answer then the call is sent to the alternate CRDAY DN
specified for that day/holiday.
Call Waiting Redirection
When Call Forward No Answer (CFNA) occurs on a waiting call, the Call
Waiting Redirection (CWTR) feature redirects the call to a specified DN
based upon the alternate days and/or holidays configured for the set. If the
current day matches one of the busy set's alternate days or holidays, then
the call is redirected to the CRDAY alternate DN.
Hunting
Hunting allows a call encountering a busy DN to route automatically to
another DN. When CRDAY is enabled and an incoming call reaches a busy
DN, the current day is checked against the alternate days and holidays
specified for that set. If the current day matches one of the alternate days,
the call begins the hunting route using the alternate redirection DNs defined
for the set.
Hunting by Call Type
The Hunt by Call Type redirects an incoming call to a HUNT DN. With
CRDAY enabled on the called DN, the incoming calls on specified Alternate
Days and Holidays are redirected to the assigned alternate HUNT DN.
Group Hunting
The Group Hunting feature provides a method of hunting DNs in a group.
The group is associated with a Pilot DN, that is, a DN with no associated
Terminal Number (TN). The hunting is done in the order of entry of DNs in
the group. If a set's list of alternate days and/or holidays program matches
the current day, incoming calls are directed to Group Hunt. This feature
allows an incoming DID call to be redirected to a Hunt DN or External Hunt
(EHT) if Call Forward by Call Type (CFCT) is enabled. To activate this
feature, the called DN must have the following class of service Hunting
Denied HTD with Hunting By Call Type Allowed (HBTA), and package 131
enabled.
