Virtual private communications network |
摘要 |
A virtual private communications network (VPCN) and method of managing calls on the network. Communications devices are networked together over a private communications network. Each VPCN communications device has a unique private network identification (ID) code and can be contacted by dialing its respective ID. At least one of the VPCN communications devices is a wireless communications device, e.g., a cell phone, connected through a public wireless network to the private communications network. Calls to and from each such wireless device pass through the private communications network.
