发明名称 CALL FORWARDING ON BUSY OR NO ANSWER WHEN CALL WAITING IS ACTIVE
摘要 A method and an apparatus for handling incoming calls when call waiting is active. If the called party is not on a call when an incoming call occurs and the called party does not answer the incoming call then a message is played to the calling party that the called party did not answer, and the called party is given the opportunity to record a message for the called party. If the called party is on a call when an incoming call occurs and, after the call waiting signal is played to the called party, the called party does not answer the incoming call then a message is played to the calling party that the called party is busy, and the called party is given the opportunity to record a message for the called party. If the called party is engaged in a first call and a second call when an incoming call occurs then a message is played to the calling party that the called party is busy, and the called party is given the opportunity to record a message for the called party. Therefore, even when call waiting is active, the calling party is properly advised of the reason that the called party did not answer the incoming call.
