Method for inserting background audio into voice/video call

A background noise inserter server is described that includes a communication interface for communicating with a network, memory for storing background audio, and a processor coupled to the communication interface and the memory. The processor controls the server to connect to a phone call session in response to a session initiation protocol (SIP) invite from a calling device indicating that the calling device is requesting the background audio in the phone call session with a called device. The processor also controls the server to insert the background audio into the phone call session so that the inserted background audio is mixed with audio from the phone call session transmitted to both the calling device and the called device.
