In one embodiment of the present invention, a method is provided for redirecting a session established between two endpoints. In such an embodiment, the method comprises receiving a SIP request to redirect the session to a third endpoint; dissociating the two endpoints; suspending a media session between the endpoints; connecting a signaling session between one endpoint and a third endpoint; and connecting the media session. In an alternative embodiment, a method is provided for referring a first endpoint to a second endpoint outside of an established dialog. In such an embodiment, the method comprises receiving a SIP REFER request specifying a uniform resource indicator associated with the second endpoint as a target; identifying a protocol associated with each endpoint; initiating a session with the first endpoint using an appropriate protocol; receiving media control information from the first endpoint; and connecting the session to the second endpoint using an appropriate protocol.
