Summary:Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for establishing communications between endpoints. In one aspect, a method includes initiating, by a first endpoint and through a call server, a call with a second endpoint. After the call is established, the first endpoint transmits, independent of the call server, first information specifying a video communication capability of the first endpoint that the call server did not setup in the established call. The first endpoint receives second information specifying that the second endpoint has the video communication capability. The first endpoint establishes, independent of the call server, video communication between the first endpoint and the second endpoint based on the first information and second information.
