To be able to forward incoming calls to other numbers, you must first add these numbers to a list for forwarding in WebEx. To do this, go to "Settings" via the cogwheel and select the menu item "Calling". Use the "+" symbol to add the numbers (preferably in E.164 format with +49 etc.).
You can then immediately activate call forwarding at this point by selecting the desired number from the list under "Forward calls to". "Save" the changes. To deactivate call forwarding, select "Do not forward calls" from the list.
Alternatively, you can also activate call forwarding to an already added number from the main WebEx window via "Call settings" (bottom left).
Click on "Call settings" and select the desired number from the list. The voicemail box must be set up by the ZIH in order to be selected. If in doubt, ask the Service Desk.
You can recognise that call forwarding is active by the small green icon with a handset and a curved arrow above it to the right of the term "Call settings".
To deactivate call forwarding, please click on "Call settings" at the bottom left of the WebEx main window again and select the "Do Not Forward Calls" entry from the list.
Please use the Cisco user portal to set more specific call forwarding settings (by time, when busy, when not registered etc.).
