| Traversal of H.323 signalling across network address translators and firewalls |
 |
This Recommendation extends H.323 to enable H.323 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 H.323 endpoints to traverse NAT/FW installations with no additional equipment on the customer premises. Alternatively, the H.460.18 extensions may be implemented by a proxy server to support unmodified H.323 endpoints. |
