Abstract: A call processing method and call processing device are provided. The method provides a media server that receives an initial call request sent by a calling terminal and forwards the initial call request to a called terminal. The media server receives a success response to the initial call request from the called terminal, and performs video resource negotiation with the called terminal.
The media server sends, based on video resource negotiation with the called terminal, a video stream to the called terminal. In an audio call process between a calling user and a called user, a video stream can be sent to the called user. This improves user experience and improves network capability utilization.
