Claim:
A method of relaying telecommunication information, comprising: receiving by a proxy call control information from a first IP-based telecommunications device, wherein the call control information comprises a header, wherein the header comprises a sender IP address, a sender identifier and a destination identifier, and a destination IP address, and wherein the destination IP address is associated with the proxy; recording the sender IP address in a database; modifying the call control information by replacing the sender IP address in the header with the IP address associated with the proxy; forwarding the call control information to a call control node; receiving from the call control node information to facilitate communication between the first IP-based telecommunications device and a second IP-based telecommunications device, wherein the second IP-based telecommunications device is associated with the destination identifier, and wherein the information comprises an IP address associated with the second IP-based telecommunications device; modifying the call control information by replacing the destination IP address with the IP address associated with the second IP-based telecommunications device and replacing the sender IP address with the recorded sender IP address; and forwarding the modified call control information to the second IP-based telecommunications device.
