1.20Integrated Services Digital Network (ISDN) Service Features
1.20.1.4Call 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:
Type | Description |
|
|
Call Forwarding— | Incoming calls are forwarded unconditionally. |
Unconditional (CFU) |
|
|
|
Call Forwarding— | An incoming call is forwarded when the |
Busy (CFB) | destination on the PBX is busy. |
|
|
Call | An incoming call is forwarded when the |
Reply (CFNR) | destination on the PBX does not answer within a |
| preprogrammed time period. |
|
|
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.
