<p>The concept of caller identification (ID) may be enhanced by taking advantage of video by allowing a call recipient to see who is calling on an incoming video call. The call recipient (120) may be allowed to make a decision to accept or decline the incoming video call based upon who the call recipient sees (i.e. caller 125) e.g. through a live video stream, attempting to contact the call recipient. The video call is set up as a two-way call however only a one-way video stream allowing video and audio to be transmitted from the caller (125) to the called party (120) is performed when a preview is requested. No video or audio is transmitted in the reverse direction. Only upon concent by the called party, after the preview, is the video call continued as a two-way call.</p> |
