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.

A communication session is established between a first communication device and a second communication device. The communication session comprises a first dialog between an application server and the first communication device. The first communication device uses a first network address in the first dialog. In response to an event, such as a first network interface failing, a SIP INVITE with replaces header message is received by the application server with a second address of the first communication device. In response to receiving the SIP INVITE with replaces header message from the first communication device with a second address of the first communication device, the first dialog between the application server and the first device is reestablished using the second network address.
