Call forwarding allows transfer or forward of calls to another phone number or directly to voicemail. If call forwarding is enabled, you can choose when you want calls to forward and who they forward to.
All calls—You can choose to have calls always forwarded to a specific phone number here. You can choose to play a brief tone whenever a call is forward by selecting the check box.
When busy—You can set up an internal or external phone number to forward to when the line is busy.
If call waiting is enabled, the when busy feature isn't triggered.
When no answer—Select this option to set up a forwarding option when a call exceeds a certain number of rings. Enter an internal or external phone number to which the call will be forwarded. If you choose a valid internal phone number, you can also select the option to send to voicemail. Select the number of rings before playing a greeting from the drop-down list.
Call Forwarding When Not Reachable (Business Continuity)—Call Forwarding When Not Reachable settings are used to forward calls if users can't be reached. For example, if your office loses connectivity, continuity settings are activated. Enter an internal or external phone number to which all calls will be forwarded. If you choose a valid internal phone number, you can also select the option to send to voicemail.
If you are using the Webex App for mobile, this feature doesn't apply.
