Point-to-point media through network address translators and firewalls within ITU-T H.323 systems Amendment 1: Improvements for NAT traversal without intermediary entities (Study Group 16)
This Recommendation defines the capability and procedures for enabling the direct point-to-point media flow between endpoints even if at least one device is behind a network address translator (NAT) or firewall (FW) device. If used in conjunction with [ITU-T H.460.23]@ this feature can be used to extend the scalability of [ITU-T H.460.19] to allow media@ where determined@ to flow directly between endpoints and avoid the requirement to proxy media.
