If you configure H.323 settings and enable H.460, the system ignores the static NAT settings
automatically.

Configuring H.460 for H.323 Protocol
If you want to make private-to-public calls via H.323 protocol, you can enable H.460 feature for H.323
protocol.
Procedure
1. 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 Method
H.460 Active
Enable or disable H.460 firewall
traversal for H.323 calls.
Default: Off.

Intelligent Traversal
Some branch offices lack IT professionals, which means that professional network configuration (for
example, the port forwarding) may be impossible. To solve this issue, Intelligent Traversal allows you to
simply deploy your VCS in the intranet, and assign an IP address to VCS, which can be used to access the
public 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 network
configuration. However, this method is not applicable to the incoming calls.

Configuring Audio & Video Intelligent Traversal
About this task
When a VCS in the intranet calls the VCS in the public network, the audio & video streams send by the VCS
in the intranet may carry the intranet IP addresses, as a result, the VCS in the public network fails to send
the audio& video streams to the VCS in the intranet. Besides, the problem of one-way audio or video and
no image of the VCS in the public network may occurs to the VCS in the intranet. The above problems can
be 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 of
incoming RTP packets, and then send the RTP packets back to the address where the incoming RTP packet
comes 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:
