Call Forwarding for users
When call forwarding for users is used, internal and external calls to single users can be rerouted to other internal phone numbers or external connections. In this way, the user in question or their substitute can take these calls on another phone.
Call forwarding for users makes sure that the user in question or their substitute is always available at his own phone number, even if the user cannot take a call on his own phone.
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 to the user are checked before a call is forwarded.
*Further help under Exchange line routing
*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.
