124 Call Forward by Call Type

ISDN Semi Permanent Connections for Australia

ISPC calls are handled according to the configuration of the route
associated to the phantom trunk TN. This configuration is independent of
the route associated to the real TN.
Message Center
Message Center uses the Flexible Call Forward No Answer DN (FDN) of the
called telephone to route no answer calls. If CFCT is enabled, unanswered
internal calls use the FDN to route a call. Unanswered external calls use the
External Flexible DN (EFD) to route a call.
Multiple Appearance Directory Numbers
Call redirection parameters like Call Forward No Answer are derived
from the TN data block of the prime appearance of the called Multiple
Appearance Directory Number. If there is more than one prime appearance,
the parameters are selected from the last TN in the DN block.
If more than one prime appearance of a MADN exists, the following
information must be considered prior to configuring call redirection
parameters for MADNs.
The DN Block organizes MADN information in numerical TN order. The TN
with the highest numerical value (000-0-06-03) is placed at the beginning of
the list. The list then continues in descending order with the lowest numerical
TN (000-0-03-01) at the end of the list. Service change activity affects the
organization of the DN list as described in the following paragraphs.
•If a telephone undergoes Service Change, its TN is moved to the
beginning of the DN list, irrespective of the numerical value. This
telephone remains at the beginning of the list until another service
change or a SYSLOAD.
•If a DN appears on analog (500/2500 type) telephones, and Meridian
1 proprietary telephones, the analog (500/2500 type) telephones are
listed in numerical TN order at the top of the list. Meridian 1 proprietary
telephones are listed in numerical TN order at the bottom of the list. A
Service Change to an analog (500/2500 type) telephone moves its TN to
the beginning of the list. A Service Change to a Meridian 1 proprietary
telephone moves its TN to the end of the list.
•A SYSLOAD restructures the list back to numerical TN order, with
analog (500/2500 type) telephones at the top and Meridian 1 proprietary
telephones at the bottom. Call redirection parameters continue to be
derived as described in the preceding paragraphs.
Recovery on Misoperation of Attendant Console
Call Forward takes precedence over the Misoperation feature.
