Breaking News Lab Transcript: RPAD 3.0 H.323 / H.460 Support

of 69 © Polycom University

Slide notes

This lab exercise demonstration will outline how to configure and use the new feature of RPAD version 3.0 that allows external endpoints to register with an internal H.323 gatekeeper with H.460 firewall traversal support.

Slide notes

There are four basic steps to this lab exercise, as outlined in your student guide.

1. We will ensure proper H.323 and H.460 configuration on the RPAD version 3.0 system

2. Then we will access the RealPresence Resource Manager version 8.0 system to configure the appropriate provisioning profile and provisioning rule to ensure external endpoints will be dynamically provisioned with the DMA gatekeeper information and H.460 firewall traversal settings

3. From outside of the corporate network, we will then sign in to a RealPresence Desktop system with an existing user account and place an H.323 call to an HDX on the corporate network

4. The final step involves viewing the active call from the RPAD, DMA and Resource Manager web interfaces

Slide 3

Slide notes

Shown here is a lab diagram depicting the Polycom infrastructure being used in this lab exercise. Once the RealPresence Platform infrastructure has been properly configured, User Two will sign into the RealPresence Desktop application on the laptop at the far left of the diagram, somewhere on the public internet. The RealPresence Access Director version 3.0 will proxy the provisioning information to and from the RealPresence Resource Manager, ultimately allowing the external endpoint to register to the corporate DMA gatekeeper and make and receive H.323 calls using alias dialing.

Slide notes

First we will access the RPAD version 3.0 system logging in with an admin account.

Slide notes

From the RPAD web interface, navigate to Configuration > H.323 Settings.

Slide notes

Check the box to Enable H.323 signaling

Slide notes

In the H.460 section, ensure the default settings of 60 and 300 seconds are intact. Since changes were made, we will click Update.

Slide notes

Click OK when prompted with the Confirm Dialog that reminds us that all active calls might be terminated.

Slide notes

The update was successful, click OK.

Slide notes

Now let's login to the RealPresence Resource Manager with an administrative account to configure the H.323 and H.460 provisioning settings.

Slide notes

The first task will be to create a provisioning profile for external endpoints that will be provisioned with the RPAD acting as Access Proxy. Let's navigate to Endpoint...

Slide notes

Dynamic Management > Provisioning Profiles.

Slide notes

Now let's Add a new Provisioning Profile...

Slide 24

Slide notes

…named External Endpoints Profile.

Slide notes

Make sure the profile type is set to Network Provisioning Profile.

Slide notes

Navigate to Firewall Settings...

Slide notes

...and check the box to Enable H.460 Firewall Traversal.

Slide notes

Set the NAT configuration to Auto.

Slide notes

Navigate to H.323 Settings...

Slide notes

...to ensure H.323 is enabled and provide the IP address of the DMA gatekeeper.

Slide notes

Click OK to save the new provisioning profile.

Slide notes

Now let's create a new Provisioning Rule that will be used to correctly apply the Provisioning Profile we just created to external endpoints accessing our Polycom infrastructure via the RPAD system.

Slide notes

Take the action to Add a new provisioning rule.

Slide notes

Name the new rule External Endpoints Rule.

Slide notes

This rule will apply our new provisioning profile to all endpoints in the RPAD network site. Now let's add the condition that must be met in order to apply the rule. Click Add.

Slide notes

The necessary condition must ensure that these endpoints are in the RPAD network site, which has already been configured on the Resource Manager. Open the drop-down Value list...

Slide notes

...and select the RPAD site from the list of existing network sites. This network site has been configured to include just the IP address of the RPAD system because each and every external endpoint traversing the firewall using this RPAD system will appear to have this exact same IP address.

Slide notes

Click OK to save the new condition.

Slide notes

Now let's select the Provisioning Profile to be applied once this condition is met. Navigate to Endpoint Provisioning Profile.

Slide notes

Select our new profile from the list of Available Profiles....

Slide notes

...and use the down arrow button to move the provisioning profile to the Selected Profiles section. Now we can click OK to save the new provisioning rule.

Slide notes

The new provisioning rule now appears in the list with an active status, as denoted by the green check mark.

Slide notes

With the RPAD properly configured and the provisioning rule in place, let's start the RealPresence Desktop application on an external laptop.

Slide notes

To receive dynamic provisioning from the Resource Manager, click on Settings...

Slide notes

...and take the option to Sign In.

Slide notes

Using the email address UserTwo@medeatalk.com, click the Next button and the application will search for the provisioning server information.

Slide notes

Notice the server has correctly been identified as rpad.medatalk.com. We will now Sign In to the provisioning server with User Two's credentials.

Slide notes

To view the results of dynamic provisioning from the Resource Manager, click the Service Connection icon in the lower left corner of the window.

Slide notes

You can see the endpoint's actual IP address, the e.164 alias that was provisioned by the Resource Manager, the Provisioning Server is listed as the Medeatalk RPAD system which is serving as an access proxy for the Resource Manager and, finally, the IP address of the DMA H.323 gatekeeper.

Click Close when finished viewing the connection details.

Slide notes

Now let's place an H.323 call to the registered HDX on the corporate LAN with an alias of 5158.

Slide notes

Enter 5158 and click the Call button...

Slide notes

...and the call connects.

Slide notes

Now let's return to the Corporate Network and monitor this call from the various RealPresence Platform web interfaces.

Slide notes

Let's start with the RealPresence Access Director system. Navigate to Diagnostics > Active Call.

Slide notes

There is currently just one active call in the list, which we can select...

Slide notes

...and then expand the Call Info pane on the right side of the window.

Slide notes

The RPAD shows the status, start time, current duration, signaling type and bandwidth. Clicking the icon will collapse this window pane.

Slide notes

Opening the Originator Pane allows us to see detailed information on the call originator, which in this case was the User Two endpoint on the public internet.

Slide notes

And, finally, let's open the Destination Window Pane. Here we can see the dialed digits of 5158 which the DMA gatekeeper resolved to IP address 192.168.2.33 on the Corporate network.

Slide notes

The RPAD also maintains a record of this call in its Call History. That view is examined in more detail in a separate lab exercise. Now let's look at this same call from the DMA Call Server.

Slide notes

This DMA Dashboard includes the Call Server Active Calls pane where you can currently see one active H.323 call.

Slide notes

Now let's navigate to Reports > Call History.

Slide notes

The Search Window defaults to today's calls, so we can click Search.

Slide notes

Select a call from the list and take the Action to Show Call Details.

Slide notes

We can now see the call details provided by the DMA Gatekeeper. Notice the network site information at the bottom of the page. User Two's RealPresence Desktop endpoint is located in the RPAD site and the Training Lab endpoint is in the CorpLAN site. As the H.323 gatekeeper, the DMA is very concerned with Bandwidth, as seen in the Bandwidth pane.

Slide notes

This pane shows the bandwidth details for this call including network site information, throttle points, bandwidth requested and final bit rate of 384K. Now let's look at Call Events.

Slide notes

This is a very similar display to the Call event listing in the RPAD. These events listed here relate specifically to the DMA's interaction with the H.323 call setup. Now let's look at the call from the RealPresence Resource Manager web interface.

Slide notes

The active call between User Two and the Lab HDX can be seen on the Resource Manager Dashboard in the Conference Status Pane. To actively manage the conference, click on Conference...

Slide notes

... Ongoing.

Slide notes

Highlight the running conference...

Slide notes

...and notice the Panes of information on the right side of the window. The Resource Manager displays information on the conference, its features and participants.

Slide notes

Take the action to Manage the conference...

Slide notes

...and the Resource Manager provides a more detailed view of the conference with additional conference

operator features, including the ability to send a message to the HDX monitor.

Slide notes

The Resource Manager can even be used to terminate this point-to-point conference by taking the action to Terminate.

Slide notes

The terminate action must be confirmed by the operator....

Slide notes

...and the call will be disconnected.

Slide notes

This concludes the lab exercise demonstration of the external H.323 registration and H.460 firewall traversal support of the RealPresence Access Director version 3.0. We completed four basic steps in this lab exercise:

1. First, we ensured proper H.323 and H.460 configuration on the RPAD version 3.0 system 2. Then we accessed the RealPresence Resource Manager version 8.0 system to configure the

appropriate provisioning profile and provisioning rule to ensure external endpoints will be dynamically provisioned with the DMA gatekeeper information and H.460 firewall traversal settings

3. From outside of the corporate network, we signed in to a RealPresence Desktop system with an existing user account and placed an H.323 call to an HDX on the corporate network

4. The final steps involved viewing the active call from the RPAD, DMA and Resource Manager web interfaces
