ABSTRACT:
A network-based call interface device is used for real-time packet protocol calls, such as, but not limited to, interfacing real-time calls between client devices and call services/destination devices. The network-based call interface device includes a virtual phone and a virtual server-phone communicating with each other. The virtual phone communicates with the call server making the network-based call interface device appear to the call server as a client device; and the virtual server-phone communicates with the client device making the network-based call interface device appear to the client device as call server.
