ABSTRACT:
A system inserts one or more background sounds in a telephone call between a calling party and a called party. The system includes a network node coupled to a first telephone used by the calling party and a second telephone used by the called party. The network node is further coupled to an audio source. One or more background sounds are stored on the audio source. The calling party dials into the network node. The network node presents a menu of background sounds to the calling party who selects at least one background sound. The calling party then enters the phone number of the called party. The network node initiates the telephone call to the called party over a first telephone channel, and then inserts the selected background sound retrieved from the audio source onto the telephone channel. If a multi-party call is requested by the calling party, the calling party can select different background sounds that are inserted by the network node onto the telephone channel for each called party.
