Disclosed are a method and device for scheduling a protocol stack in a telepresence system. The scheduling method includes: a telepresence endpoint acquiring a first state of an H.323 protocol stack and a second state of a third-party protocol stack, herein, the third-party protocol stack is used for performing interaction and negotiation on new characteristic parameters of the telepresence system, and the new characteristic parameters are different from contents for performing capability negotiation through the H.323 protocol stack in the telepresence system; the telepresence endpoint scheduling the H.323 protocol stack and/or the third-party protocol stack to execute a corresponding internal processing action according to a preset scheduling rule based on the first state and/or second state.
