You can optionally create a group named Operator and populate it with members—either groups or users—who are always available, such as store operators or the front desk.
Vocera provides quick access to an Operator group for callers who dial the Vocera hunt group or DID number. If a caller enters 0 (for Operator) when prompted by the Genie, Vocera directs the call to the Operator group. If you specify a forwarding number for the Operator group, you can redirect the call if no group member is available. For example, you can forward calls to the 0 extension on your PBX.
