Abstract
A system, method, and computer program product through which address resolution is performed for nodes of a network that are behind a network address translator (NAT). A determination is made upon the initiation of a communication session as to whether one or more of the nodes included in the session are behind a NAT. Based on the determination, information is exchanged from an independent application server to the nodes included in the session so as to resolve the addressing problems introduced by the NAT. The invention is applicable in applications including, but not limited to, IP telephony, and applications complying with the session initiation protocol (SIP).
