Abstract: A method, a device, and a system for implementing an electronic whiteboard in an audio/video conference are provided. The method includes the following steps. An electronic whiteboard is created. A first extended message is sent to a first user equipment (UE) and a second UE in a Session Initiation Protocol (SIP) audio/video conference, so as to instruct the first UE and the second UE to initialize the electronic whiteboard. A second extended message containing an operation instruction of the electronic whiteboard sent by the first UE is received. The second extended SIP INFO message is sent to the second UE. Thus, a function of the electronic whiteboard is integrated in an SIP audio/video conference.
