Abstract: Methods and systems disclosed provide for creating private networks for secured communication between devices. The devices can communicate with each other over a secure tunnel created for a closed circle of devices. Furthermore, the methods and systems can enable offline communication between devices on a private network.

Abstract: Described is a conferencing system having a conference service, a Web-based service and an IP-telephony service, which enable the conferencing system to provide communication functions, such as conferencing and chat-room functionality, in response to at least one menu selection or menu navigation command received by a user interface. This user interface is comprised of components that render it compatible with a communications device that generates DTMF signals, such as a telephone or IP telephony-enabled client. These components may include an interactive voice response (IVR) module and a menu navigation module.
