relating the telephone number to an IP address associated with the telephone number;
sending an invitation to the IP address;
receiving a response to the invitation; and
modifying and forwarding the response to the first telephony device, such that the modified response contains a first IP header including a first IP address of the first telephony device and a second IP header including a second IP address of the first telephony device, wherein the first IP address indicates a point of connection of the first telephony device to a network, and wherein the second IP address is generated as a result of registration of the first telephony device with a voice home agent.
