    This Recommendation extends H323 to enable H323 devices to successfully exchange signalling
    and establish calls, even when they are placed inside a private network behind NAT/FW devices
    These extensions, when used together with the facilities of H.460. 19, enable H323 endpoints to
    traverse NAT/F W installations with no additional equipment on the customer premises
    Altemnatively, the H460.18 extensions may be implemented by a proxy server to support unmodified
    H. 323 endpoints
