Abstract:
A system and method for conducting a video call between an originating device and a terminating device by establishing a peer-to-peer (P2P) connection between the devices. The originating and terminating devices exchange candidate information through a P2P server, except that the candidate information for the terminating device is altered before arriving at the originating device. The altering includes changing the IP address and corresponding port for each candidate. The originating device uses the altered candidate information to derive new candidate pairs that are sent to the terminating device, which uses the new candidate pairs to also derive a second candidate list. If the candidate pairs match, a P2P connection is established between the devices.
