Abstract: Privacy is often a concern when conducting a voice-based communication over a network. Users who utilize a speakerphone may provide an opportunity for unwelcome third parties to overhear the far-end portion of the call. By establishing a Session Initiation Protocol (SIP) media session utilizing signaling comprising a transducer header, a called device may utilize the desired transducer to better facilitate privacy (e.g., headset, handset). If privacy is not requested, the transducer header may indicate any transducer may be used or that use of a speakerphone is permitted. Mid-call changes in the requested privacy may also be accommodated to request transition to or from a more private transducer utilized by the far-end device.

Abstract: Embodiments disclosed herein provide systems, methods, and computer readable media for maintaining feature settings across user systems. In a particular embodiment, a method provides, in a first user system having a first feature set, exchanging communications for a communication session using first settings of features in the first feature set. The method further provides determining a current state of the first settings before a second user system having a second feature set joins the communication session and configuring second settings of the second feature set that correspond to the first settings in accordance with the current state. In the second user system, the method provides exchanging communications for the communication session using the second settings of the second feature set.
