associating with each one of a plurality of users a set of video endpoints, each set comprising a preferred video endpoint, and the set associated with a first user comprising a substitute video endpoint in addition to the preferred video endpoint; starting the video conference by creating a communication link between a processor configured to offer a virtual room and the preferred video endpoint of each of the sets associated with the plurality of users; switching, during the video conference, a first communication link between the virtual room and the preferred video endpoint of the set associated with the first user to a second communication link between the virtual room and the substitute video endpoint of that set, wherein an identity and credentials of each user are maintained separately from an identity and credentials of each endpoint in the set of endpoints associated with that user; and recognizing the identity of the first user after switching, even though, the identity of the preferred video endpoint associated with the first user is different than the identity of the substitute video endpoint associated with the first user. |
