The embodiment of the invention discloses a method, equipment and a conference
system of a call progress state. The method adopts the technical scheme that sending a calling request to a called terminal; acquiring
multimedia prompting information of the call progress state; sending the
multimedia prompting information of the call progress state to a
conference control equipment management platform and / or a conference terminal so as to ensure that the
conference control equipment management platform and / or the conference terminal outputs a corresponding progress state
multimedia prompt according to the multimedia prompting output information of the call progress state. Compared with the prior art which converts received mark information into call failure reason voice information through the
conference control equipment management platform and the conference terminal, because both the conference
control equipment management platform and the conference terminal are not used for storing prompting information resources, the embodiment saves the storage resources of the conference
control equipment management platform and the conference terminal. The invention adopts various prompting
modes and enables the prompting information to be more abundant.
