Abstract: A voice over Internet protocol processing method and a related network device are disclosed. The method includes: detecting, by a calling access network element, an off-hook event; encapsulating, by the calling access network element, the off-hook event into first signaling; sending, by the calling access network element, the first signaling to a cloud server; receiving, by the calling access network element, second signaling sent by the cloud server, where the second signaling is used to establish a first transmission path between the calling access network element and the cloud server, and the first transmission path is used to transmit data between the calling access network element and the cloud server; and establishing, by the calling access network element, the first transmission path based on the second signaling. Overall efficiency of the voice over Internet protocol system can be improved, and the construction costs can be lowered.

Abstract: This application provides a distributed data transmission method, an apparatus, and a system. When sending RTP data to an output device, an input device determines a delay time of a first output device and a delay time of a second output device based on a device delay control list, and sends the RTP data to the first output device and the second output device based on the delay time of the first output device and the delay time of the second output device, so that times for the first output device and the second output device to output the data are the same. The times for the first output device and the second output device to output the data are controlled. Thus, the first output device and the second output device can output the data simultaneously.
