1.20.1.5Call Forwarding (CF)—by ISDN (P-P)
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.
The network directly forwards the call to the destination which the extension user has set on the PBX as the forward destination of trunk calls; the network is instructed by the PBX. This feature is available only when the call is received through an ISDN port which supports this feature.
Call
This feature complies with the following European Telecommunication Standard (ETS) specifications: ETS 300 207 Diversion supplementary service.
