For signal transmission from phone to telephone requires a special device - IP gateways. This is the device through which the stream of data from one network type to another network type. IP gateways or as they are called IP servers on the one hand are connected to phone lines and can connect with any phone in the world and the other - with the Internet due to which unable to contact anyone connected to the Internet computer.
