Before you can register your Poly endpoint to StarLeaf, you must first add it to the StarLeaf Portal. Refer to How to add an H.323 endpoint to the StarLeaf Portal.

To configure the H.323 settings of the Poly endpoint, you must access its web interface and make some changes. The example here is the Polycom HDX 8000.

  1. Find the IP address of the Poly endpoint. It is at the bottom of the Poly display:

  2. Navigate to the IP address in your browser; you are prompted for a username and password. The default username is admin and the default password is the serial number of the HDX. If the default settings do not work then contact your system administrator.
  3. To edit the H.323 settings go to Network > IP Network. H.323 Settings appear at the top of the screen.

  4. Use the following settings:
    • H.323: enabled
    • H.323 Name: this is the H.323 ID / name from the Portal
    • H.323 Extension (E164): this is the H.323 ID / name from the Portal
    • Use Gatekeeper: choose Specify
    • Authentication: check the box and enter the Authentication name from the Portal. Check the Password box and enter the Authentication password you entered in the Portal. This is optional and you don’t need to set the authentication
    • Primary Gatekeeper IP Address: enter the IP address and default port of the Portal gatekeeper service.
      • To find the IP address of the Portal gatekeeper service, you must ping your organization’s StarLeaf subdomain. That is, ping [your organization name] For example, here at StarLeaf, we would ping, which returns an IP address of
      • The default port is 1719. Use this format:
        IP address:1719
        For example:
    • Enable SIP: disabled
    • Enable H.460 Firewall Traversal: enabled
  5. Click Update to save all changes, then restart the hardware. Check the Diagnostics page to verify that the Gatekeeper status is up.
  6. To test the configuration, call the H.323 ID of the endpoint from any StarLeaf device. If the call does not work, reboot the endpoint and retry.

NAT settings on H.323 endpoints (where you enter the public IP address of your gateway onto the endpoint itself) needs to be disabled. The purpose of these settings is to assist firewall traversal, but they can interfere with proper operation of the H.460 protocol.


  • If the calls between the registered Poly endpoint and StarLeaf are audio only, check that Basic/Diagnostic Mode is not active in the settings. The setting can be found under Admin Settings > Network > Call Preference. After changing the setting, the Poly endpoint needs to be rebooted.
  • If the gatekeeper fails to register after a device reboot, or change of IP address, it is probably because the Poly endpoint has forgotten the H.460 firewall traversal setting. Find the setting under Admin Setting > Network > IP Network > Firewall, and uncheck, then re-check the option.

Configuring the endpoint to display the directory

This is an example LDAP endpoint configuration. To configure the directory on the Polycom HDX 8000, go to Admin Settings > Global Services > Directory Servers.
