When DID or an Auto Attendant is used, users receive calls directly, without the intervention of an operator. In these situations, the telephone should have voice mail coverage instead of coverage by a receptionist (operator). The caller then has the option to leave a message or press 0 in order to talk to the receptionist. If after talking to the receptionist, the caller wants to leave a message, the receptionist can transfer the call back to voice mail using the Direct Voice Mail (DVM) feature.
