The present disclosure provides a method for processing a system call in a voice call. The method includes: participating, by a first terminal, a voice call with one or more second terminals, the voice call being performed in a non-system voice call application on the first terminal; monitoring, by the first terminal, a system call start event during the voice call; actively stopping, in response to the system call start event, use of an audio device of the first terminal; suspending participation of the first terminal in the voice call; sending, by the first terminal, a voice suspension request to a server to remind the one or more second terminals that the first terminal suspends the voice call; and recovering the voice call when the system call ends.
