发明名称 Variable-time call forwarding to voicemail
摘要 Unanswered calls route to voicemail after a variable number of ring cycles based on a history with the voicemail user. The history may include the caller's identity, the user's answering history, and user preferences. If the caller is not identified, an unanswered call may go to voicemail after a default number of ring cycles. If a caller has a history of previous calls to the user/called party, that history may increase or decrease the default number of ring cycles for that caller. For example, callers whose previous calls to the voicemail user have been answered may receive more ring cycles before going to voicemail. Conversely, callers whose previous calls to the user/called party were unanswered may receive a reduced number of ring cycles before going to voicemail. The number of ring cycles may also be adjusted where the call answering history suggests the called party is unavailable during certain times.
