Abstract:
A method, computer program product, and computer system for establishing a Voice over IP (VoIP) session. One or more computing devices initiate the VoIP session between a plurality of devices. A first communication channel is established as an active channel for a first computing device of the plurality of devices, where the active channel is fully enabled for use by the first computing device. A second communication channel is established as a passive channel for the first computing device while maintaining the active channel, where the passive channel is at least partially enabled for use by the first computing device.
