Abstract
A system and method to allow multimedia (voice and video) data communication to pass through enterprise firewalls and proxy, which include network address translator (NAT). The system also includes servers to redirect voice/video data packets to other VoIP standard conforming servers. The redirect server sends command and data either using transmission control protocol (TCP) or user datagram protocol (UDP), depending on the configuration and protocol requirements of each server. This method is compatible with the existing communication standards, such as ITU H.323, session initiation protocol (SIP), media gateway control protocol (MGCP) and media gateway control (MEGACO).
