METHOD AND SYSTEM FOR PUTTING A TELEPHONE CALL ON HOLD AND DETERMINING CALLED PARTY PRESENCE |
摘要 |
When a call is placed to an organization seeking information from a representative of that organization, the call is frequently placed on hold for an extended period of time. After the call is made and the called party's telephone is placed on hold, the caller enters a code signal to place the call on hold. At this instant, both telephones are on hold. At some time after this "Hold On Hold" connection is established when a representative of the organization called answers the telephone and speaks to identify himself, the network identifies the signals as being generated by a live person, and a ring signal is sent to the caller's telephone to alert the caller that the call is no longer on hold. |
