Abstract
In a VoIP application where network packets must travel beyond the local internet provider, the network packet may be rerouted to avoid the open internet. The originating endpoint is provisioned to transmit network packets to the VoIP provider. The originating local internet provider receives the network packet from the originating endpoint, and transmits the network packet to the VoIP provider via a direct hand-off. The VoIP provider then transmits the network packet to the destination local internet provider via a direct hand-off. Finally, the destination local internet provider delivers the network packet to the destination end point. Transmission through the open internet is reserved as a back-up process, should transmission through the VoIP provider fail.
