The method includes receiving, by the gateway, a call initiated by the terminal device; negotiating, by the gateway, with the terminal device, to establish a first call between the gateway and the terminal device and determine a media type of the first call; and adding the negotiated media type of the first call to a call established between the gateway and the MCU, where the media type of the first call is different from that of the established call. In this way, the negotiated media type of the call is added to the call established between the gateway and the MCU."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Call processing method and gateway","description":"A call processing method and a gateway are disclosed, where the gateway is configured to process a call between a multipoint control unit (MCU) and a terminal device.
