Setting H.323 Endpoint Registration Timeout

You set an endpoint registration timeout to specify how long an endpoint registration entry remains in the NAT table

In NAT mode, when endpoints in the protected network behind the J-series device register with the H.323 gatekeeper, the device adds an entry to the NAT table containing a mapping of the public-to-private address for each endpoint. These entries make it possible for endpoints in the protected network to receive incoming calls. To ensure uninterrupted incoming call service, set the endpoint registration timeout to a value equal to or greater than the keepalive value the administrator configures on the gatekeeper. The range is 10 to 50000 seconds, the default value is 3600 seconds.

To set the H.323 endpoint registration, use either J-Web or the CLI configuration editor.

4. Next to H323, click Configure or Edit.
5. In the Endpoint-registration-timeout box, type 5000 and click OK.
6. If you are finished configuring the J-series device, commit the configuration.
7. To check the configuration, see Verifying the H.323 Configuration.

CLI Configuration

In this example, you set the endpoint registration timeout to 5,000 seconds.

If you are finished configuring the J-series device, commit the configuration.

To check the configuration, see Verifying the H.323 Configuration.
