发明名称 Methods, Systems, and Products for Providing Ring Backs
摘要 Methods, systems, and products are disclosed for providing a ring back to a calling party's communications device. A first call is placed to a called number. An identification sequence is received during the first call. When the first call ends, a second call is placed to a server. The identification sequence is sent to the server during the second call, and the ring back associated with the identification sequence is received. The ring back is stored in memory of the calling party's communications device and retrieved when subsequent calls are made to the called number. The ring back is then presented on the calling party's communications device to indicate the called number is ringing.
