Abstract

A computer program product for managing communications during a videoconference includes computer executable instructions stored on a computer readable storage medium that when executed by one or more computers causes the one or more computers to receive an input first set of communications control parameters that apply to all videoconferences to be conducted over one or more videoconference servers. The computer stores the input first set of control parameters in a memory, and receives an input second set of communications control parameters that includes a subset of the first set and that applies to only a portion of videoconferences to be conducted over the one or more videoconference servers. The computer compares the second set of communications control parameters to the first set of control parameters and retains the second set of communications control parameters in a memory for use during the conference if they do not violate the first set of control parameters.

12. A computer program product for managing communications during a videoconference as defined by claim 11 wherein there are a plurality of users registered with the conference server for participating in videoconferences over the conference server, wherein the second set of parameters specifies only a portion of the plurality of users that is less than all of the plurality of users and wherein the second set of parameters applies only to the portion of the plurality of users, and wherein the third set of parameters applies only to one specified videoconference held over the conference server.

13. A computer program product for managing communications during a videoconference as defined by claim 10 wherein the program further causes the one or more computers to:
