Abstract
A cellular telephone includes a speaker, a microphone and voice channel establishing components for opening a voice channel between the cellular telephone and a source telephone requesting communications with the cellular telephone without opening the speaker and microphone. Thus, voice communications between the cellular telephone and the source telephone are prevented until a predetermined signal from the user of the cellular telephone is received. The cellular telephone also include delayed speaker and microphone connecting components for receiving and processing data from the source telephone without opening the speaker and the microphone. The data may include the identity of the source telephone or a message which may be displayed for the user of the cellular telephone. Based upon the identity of the source telephone, the user of the cellular telephone may selectively ignore or respond to the request for communications, or may route the request to an automated answering device or another telephone.
