There is not much happening when you video call. A live video is just streamed to the person on the other side and the same for the other guy as well. Answering to Batu - The Call, even though it takes time to record and answer, happens so instantaneously, that the time lag is not noticed very often. There is a delay of about 2-3 seconds on a slow broadband connection, but on a 3G or 4G network, there is a very small delay of 500-600 ms. Nowadays, almost all networks and fiber broadbands give a delay of < 300ms. It is a live video. A snap is nothing but a series of Pictures captured at a fast rate along with audio. A video without an audio layer would be useless. So it is surely a video.
