ABSTRACT:
A method and apparatus for managing incoming and outgoing calls at an endpoint placed on hold are disclosed. A first call that includes an outbound media stream is established on a network between a first endpoint and a second endpoint. The first endpoint detects that the first call was placed on hold by the second endpoint and a second call between the first endpoint and a third endpoint after detecting that the first call was placed on hold. The first endpoint communicates the outbound media stream in the second call and mixes a first incoming media stream from the first call with a second incoming media stream from the second call for presentation to a user of the first endpoint.
