Abstract
In an embodiment, a communication device receives a request to establish a media session with a remote endpoint. In response to receiving the request, the communication device exchanges media-session control data with the remote endpoint on behalf of a local endpoint to establish the requested media session between the local endpoint and the remote endpoint. The communication device is communicatively connected to the local endpoint via a Personal Area Network (PAN) communication link. The communication device relays media-session payload data between the local and remote endpoints. The media-session payload data (i) is associated with the media session and (ii) is encrypted based on at least one payload-data cryptographic key that is not accessible to the communication device.
