Call Forwarding for Groups
When call forwarding for groups is used, internal and external calls to a group can be rerouted to other internal phones 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.
Note: LCR will be used for call forwarding for groups to an external destination (e.g., mobile phone) if at least one member of the group has LCR enabled. It does not matter if the corresponding subscriber is logged in or not. Note: When forwarding a group the option As subscriber in the exchange line settings of the group is not considered. For call forwarding instead exchange line authorisation is not restricted and no call restrictors and call deblockers are used. Note: Preferred exchange line/Number Presentation: The number of the group is always presented. 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 (page Subscriber (scr.) > Properties > Authorisations)
Note: The forwarding subscriber needs an authorisation e.g. for group call forwardings. 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 (page 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 (page Groups > Properties > Reachability)
-Using a character string on the internal phone (see Call Forwarding for Groups)
• Making additional settings for call forwarding.
-Using the Configuration Manager (page Groups > Properties > Reachability)
• Configuring the call forwarding configuration dependent.
-Using the Configuration Manager (page Groups >Profiles > ... > Reachability)
