Users can screen incoming calls while the phone is in an idle state and listen to incoming calls transferred to voicemail. When an incoming call arrives at a phone and is directed to and answered by the voicemail system, the user automatically hears the caller on his or her phone speaker, but the caller cannot hear the user. Users can decide whether to answer the call or drop from the call and let the voicemail system continue to handle the call. A user cannot screen a call while he or she is on another call.
