摘要：
A first communication device receives a communication from a second communication device. The communication could be part of the signaling used to establish a call to the second communication device or an audio signal that the second communication device conveys after its user has answered the call and started speaking. Based on the communication from the second communication device, the first communication device provides a user-discernible indication regarding the environment in which the second communication device is being used, such as an indication that the second communication device is being used with a speakerphone. If the second communication device is being used in a vehicle, the first communication device may also provide a user-discernible indication regarding the operational status of the vehicle, such as whether the vehicle is in motion and/or the number of occupants in the vehicle.
