Abstract: A system for controlling access to enterprise software on a premised-based server or running as a cloud service for a plurality of end users that includes a first tier Administrator, a second-tier Administrator, a user interface, a database, and a per seat license. The first-tier Administrator identifies a community that can access the cloud service and an upper limit of end users that can belong to the community. The second-tier Administrator is selected by the first-tier Administrator. The second-tier Administrator can create at least one Organizational Unit that is a subset of the end users within the community. The user interface includes all the Organizational Units, and each Organizational Unit corresponds to a particular cloud service. The database is controlled by the first-tier Administrator, and it controls the end users that can access the cloud service.

Abstract: A system and method for supporting a multi-participant voice conference call using PSTN and Internet networks is described. The method for supporting a multi-participant voice conference call includes receiving voice from a PSTN client. The method also includes receiving voice data from a moderator and from at least one remote client connected to the Internet. The method then proceeds to mix the voice data from the PSTN client with the voice data from the moderator into a first mixed voice data that is transmitted to the remote client that is connected to the Internet. The method also mixes the voice data from the moderator with the voice data from the remote client connected to the Internet into a second mixed voice data that is transmitted to the PSTN client.

Abstract: A multi-participant conference system and method is described. The multi-participant system includes a PSTN client, at least one remote client and a first participant client. The PSTN client communicates audio data and the remote clients communicate audio-video data. The first participant client includes a voice over IP (VoIP) encoder, a VoIP decoder, a first audio mixer, and a second audio mixer. The VoIP encoder compresses audio data transported to the PSTN client. The VoIP decoder then decodes audio data from the PSTN client. The first audio mixer mixes the decoded audio data from the PSTN client with the audio-video data from the first participant into a first mixed audio-video data stream transmitted to the remote client. The second audio mixer mixes the audio-video data stream from the first participant with the audio-video data stream from each remote client into a second mixed audio transmitted to the PSTN client.
