Call Forwarding for Subscribers
When call forwarding (CF) for subscribers is used, internal and external calls to a single phone can be rerouted to other internal phones or external connections. In this way, the subscriber in question or his replacement can take these calls on another phone.
Call forwarding for subscribers makes sure that the subscriber in question or his replacement is always available at his own phone number, even if the subscriber cannot take a call on his own phone.
Note: To avoid having to use a second call channel in the case of call forwarding to an external destination, the PBX tries to reroute the call directly at the network provider using call deflection. The following requirements must be fulfilled for this purpose: 1. The incoming call was made via an ISDN or a VoIP network provider supporting call deflection. 2. The rerouted phone number is neither called as a group member, nor is it required to consider parallel calling or fallback on busy.
Proceed as follows for configuration:
•Switching authorisations for the involved internal subscribers on.
−Using the Configuration Manager (Subscriber (scr.) > Properties > Authorisations)
Note: The forwarding subscriber needs an authorisation e.g. for external destinations. For configuring using a character string on an internal phone the subscriber needs an authorisation for controlling of the PBX.
•Configuring sufficient exchange line authorisations for the involved internal subscribers.
−Using the Configuration Manager (Subscriber (scr.) > Properties > Exchange line settings)
Note: The destination subscriber needs a sufficient exchange line authorisation for taking external calls.
•Switching call forwarding on.
−Using the Configuration Manager (Subscriber (scr.) > Properties > Reachability)
−Using the menu/function key on a system phone (optional, see the phone manual)
−Using the menu/T-Net function key on an analogue T-Net phone (optional, see the phone manual)
•Making additional settings for call forwarding.
−Using the Configuration Manager (Subscriber (scr.) > Properties > Reachability)
•Configuring the call forwarding configuration dependent.
−Using the Configuration Manager (Subscriber (scr.) >Profiles > ... > Reachability)
