1.20.1.4 Call Forwarding (CF)—by ISDN (P-MP)
Description
An extension user can forward the incoming ISDN call to another outside party using the ISDN
service of the telephone company, instead of the PBX feature, when the call is received through
an ISDN line.
Extension users can set the forward destination to the network on an MSN basis. The setting
must have been done beforehand to use this feature. There are the following types:
When the CFB or CFNR has been set, the network determines to forward the incoming call to
the preprogrammed destination after the call reached the PBX once. When the CFU has been
set, the network forwards the call directly to the preprogrammed destination.
This feature complies with the following European Telecommunication Standard (ETS)
specifications: ETS 300 207 Diversion supplementary service.
