| Traditional Deployment Methods | 50If you configure H.323 settings and enable H.460, the system ignores the static NAT settingsautomatically.• Configuring H.460 for H.323 ProtocolConfiguring H.460 for H.323 ProtocolIf you want to make private-to-public calls via H.323 protocol, you can enable H.460 feature for H.323protocol.Procedure1. Do one of the following:• On your web user interface, go to Account > H.323 > H.460 Active.• On your VCS, go to More > Setting > Advanced > H.323 > H.460.On your VP59, tap Setting > Advanced > H.323 > H.460.• On your CTP20, tap Setting > Advanced > H.323 > H.460.2. Configure and save the following settings:Parameter Description Configuration MethodH.460 Active Enable or disable H.460 firewalltraversal for H.323 calls.Default: Off.Web user interfaceEndpointCTP20Related tasksSetting H. 323 Account/H.323 IP CallIntelligent TraversalSome branch offices lack IT professionals, which means that professional network configuration (forexample, the port forwarding) may be impossible. To solve this issue, Intelligent Traversal allows you tosimply deploy your VCS in the intranet, and assign an IP address to VCS, which can be used to access thepublic network. After that you can place calls to the VCS in the public network via your intranet VCS.This type of deployment is simple to deploy, plug and play, and does not require complex networkconfiguration. However, this method is not applicable to the incoming calls.• Configuring Audio & Video Intelligent Traversal• Configuring Data Intelligent TraversalConfiguring Audio & Video Intelligent TraversalAbout this taskWhen a VCS in the intranet calls the VCS in the public network, the audio & video streams send by the VCSin the intranet may carry the intranet IP addresses, as a result, the VCS in the public network fails to sendthe audio& video streams to the VCS in the intranet. Besides, the problem of one-way audio or video andno image of the VCS in the public network may occurs to the VCS in the intranet. The above problems canbe solved by the feature of audio & video intelligent traversal.This feature allows the VCS in the public network to check the media source address and the port ofincoming RTP packets, and then send the RTP packets back to the address where the incoming RTP packetcomes from rather than the address provided in the Session Description Protocol (SDP).The following example illustrates a scenario about using the audio & video intelligent traversal:
