Configuring the SBC Edge for a Single CCE

READ BEFORE BEGINNING

You must follow these steps completely and in the order shown. Failure to do so increases the risk of node failure.

In this section....

For details on troubleshooting, see Troubleshooting Cloud Connector 6.1.2.

This page provides a step-by-step procedure for Non High Availability Deployment on SBC Edge CCE.

Before You Start

CCE Deployment Scenarios

The following diagram shows typical CCE deployment scenarios on a PSTN site. The PSTN site is a combination of Cloud Connector instances, deployed at the same location, and with common PSTN gateways pool connected to them. PSTN sites allow you to:

Provide connectivity to gateways that are closest to your users.
Allow for scalability by deploying multiple Cloud Connector instances within one or more PSTN sites.
Allow for high availability by deploying multiple instances of Cloud Connector within a single PSTN site.

CCE Deployment Scenarios

Scenario 3 and Scenario 4 are covered in Configuring the SBC Edge for Two CCEs. This document contains steps for Scenario 1 and Scenario 2 deployments.

Prerequisites

A public domain name prepared and mapped with your Office 365 tenant (for example, "mydomain.com"). See Create an Office 365 Tenant.

An entry on your public domain name that points to the fixed IP address of your SBC Edge (for example, myccesite1.mydomain.com" with an IP address of "nn.nn.mm.nn").

An Office 365 tenant with an E5 license or E3 + Cloud PBX.

You must have the Global Administrator role for your O365 tenant account.

A public certificate authority ready to sign a certificate for the SBC Edge.

Important! Read the steps outlined in Certificate Requirements at Microsoft Technet.

A properly configured firewall. See Ports and Protocols at Microsoft Technet.

MANDATORY!

If activation fails, check the following:

If access to the Microsoft Server fails, verify IP and Firewall configuration.
Verify each Product Key has not reached the allowed limit of 15 activations.
Verify correct entry of the Product Key.

Set CCE Private Certificate

This step synchronizes the CCE and SBC CA Certificate, or Renews the CCE CA or CCE Certificate.

This feature applies to SBCs running ASM with the Office 365 Cloud Connector Edition image.

If you configure TLS and downgrade the system to a release prior to Release 7.0, the Exchange CA Certificate for TLS will be unavailable; you must re-deploy or upgrade to Release 7.0. Along with TLS configuration on the CCE, the TLS capability requires a loaded Root CA certificate and a signed certificate on the SBC.

These instructions assume the SBC Edge already includes a valid Trusted CA (which issues the Sonus SBC Certificate). For more information, refer to Working with Certificates.

You will not be able to complete Step 4: Synchronize CCE/SBC CA Certificate without a valid Trusted CA in SBC Edge.

Step	Action
1	Login to the WebUI of the SBC Edge.
2	Navigate to Tasks > Office 365 Cloud Connector Edition and click the CCE Private Certificate tab.

Installing the CCE Appliance using Sonus Cloud Link Deployer

CCE Deployment - Using a Proxy on the ASM Host

If you plan to use a proxy on the ASM Host to reach Office 365, you must add the Management network (192.168.213.0) into the exclusion list and specify proxy settings per machine rather than per user.

CCE Deployment - What to Expect

The CCE deployment may exceed two hours.
The CCE deployment status is visible only on the Remote Desktop to the ASM. The WebUI indicates that the CCE is running while the deployment process is in progress.
While the CCE deployment is running, you should not perform any actions on the ASM via the WebUI (i.e., Shut Down/Reset/Reboot/Reinitialize/Install etc.).
If the Office 365 PSTN Site already exists in your tenant, ensure the other Appliance is removed, and the CCE Auto-Update time window is properly configured. If you are in a time window dedicated to the Auto-Update, you should use the command Set-CsHybridPSTNSite to set EnableAutoUpdate to $False. Replication of the information may take up to 30 minutes.

Step

Action

1

Remote desktop to the ASM system.

2

Launch the Sonus Cloud Link Deployer from icon on the desktop.

3

Check the first three actions:

Transfer Password from SBC: This step imports the password that has been set during the Preparing the CCE.

Backup the Public Certificate per Tasks > Setup Cloud Connector Edition> Import Certificate.

Clean Office 365 tenant

If the CCE was previously deployed, previously installed information must be cleared in O365. To do so, follow the steps below:

Step	Action
1	Remote Desktop to the ASM system
2	Connect the Office365 Tenant through a series of commands as follows: a. Execute the following command: `Import-Module skypeonlineconnector` `$cred = Get-Credential` b. When prompted, execute the credentials for O365 Admin Tenant. c. Execute the following command: `$Session = New-CsOnlineSession -Credential $cred -Verbose` `Import-PSSession $session`
3	Display all the Appliances assigned to your tenant, identify the Appliance you just re-initialized, and copy the identity into your clipboard. `Get-CsHybridPSTNAppliance`
4	Execute the following command to remove the appliance: `Unregister-CsHybridPSTNAppliance -Identity <paste the identity here> -Force`
5	Execute the following command to verify that the appliance has been removed: `Get-CsHybridPSTNAppliance`
6	This completes the cleanup.

Re-Initializing of the ASM

The ASM must be re-initialized with the image that contains the latest CCE software . To do so:

Step	Action
1	Login to the WebUI of the SBC Edge.
2	Click the Task tab, and then click Reinitialize in the navigation pane.
3	Select the appropriate image from the drop-down list and then click Apply.

Manually Managing the CCE Configuration File

Editing the CCE Configuration File

The “.ini” file is the configuration of the Microsoft CCE (Cloud Connector Edition) running on the ASM. The contents of the ".ini" file must be as defined by Microsoft. From the Configure CCE panel, the Raw INI Config drop-down list enables you to edit, export, or import the ".ini" file.

Working with the ".ini" file allows you to provision multiple CCEs in a similar manner. Once you configure a CCE, you can export the ".ini" file, modify it for the second system, and then import the CCE. This procedure can then be repeated for the third system, etc. Also, backing up the SBC configuration and CCE configuration helps recover faster in the case of lost data.

Step	Action
1	After receiving the activity status completion message, click the Click to re-configure CCE application button.
2	Click OK on the popup.
4	Click the Raw (INI) Config drop-down list, select Edit. Configurable fields are displayed for editing. Modifications to the CCE configuration requires redeployment of the CCE VM, and this action takes approximately two hours. Note: The example uses AEPSITE2 for the these attributes.
5	After verifying the information click OK.

Importing and Exporting the CCE Configuration File

Step

Action

1.

After receiving the activity status completion message, click the Click to re-configure CCE application button.

2.

Click OK on the popup.

3.
