When call forwarding for groups is used, internal and external calls to a group can be rerouted to other internal telephones or external connections. In this way, a person that is not a member of this group and therefore cannot log in, can receive these calls.
Call forwarding for groups makes sure that someone is always available on the group number, even if the calls cannot be taken by a member of the group.
For call forwarding to an external number: The external destination must be reachable for the user. For this, the exchange line routing settings (with block- and allowlist) that apply for the group are proved before a call forwarding is executed.
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 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.
