Configuring the SBC Edge for a Single CCE

 

 

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

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.

 

 

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

Network Settings

For this best practice, Cloud Connector Edition deployment follows the cabling shown below: 

Firewall Settings

For this best practice, the Router/Firewall is configured using the following rules: 

DNS Settings

Make sure that CCE FQDN is resolving to the

Public IP address. To do so, login to your DNS server and create the relevant entries.

Preparing Your Node

Preparing the

for Initial Setup

Update the

firmware to the latest released version.

Sonus recommends starting with a clean and empty configuration. During the initial setup, 

must be configured with two IP interfaces: one for the internal company network (corporate network), and the second one for the DMZ network (Internet network) as shown below:

Preparing the ASM

If your ASM have been used before, you should re-Initialize it now. Refer to Re-Initializing the ASM for details.

Confirm that the ASM is ready to deploy the Cloud Connector Edition. To do so:

 

After you update the ASM, change its Admin Password.

Deploying the CCE

Deploying CCE 1.4.1 on the

consists of two steps:

2. Microsoft PowerShell tasks running on

   ASM by executing CCE specific Microsoft commands.
   
   

 

Configuring the CCE Through the WebUI

ASM Config

Generating the CSR

This process is required only if you don't have a public certificate for your deployment. If you already have a certificate, proceed to Import Certificate.

Manually Configuring the CCE on the ASM

Manually deploying CCE on the ASM requires:

• Registering the CCE Appliance with PowerShell
• Installing the CCE Appliance with PowerShell

Installing the CCE With PowerShell

After configuring the

for CCE, refer to Managing Your Office 365 Tenant to configure CCE update time and user.

Integrating the SBC Edge With Cloud Connector Edition

After the CCE is deployed, integrate the  Sonus Sbc Edge and allow calls from/to O365 clients. In this example, the following steps will set up the Sonus Sbc Edge for:

Build your SBC configuration

 

Build your Second SBC Configuration (Optional)

Integration

With the preceding settings, an endpoint from the SIP provider side can dial the number of a Skype For Business (O365) client and reach out to it over

. The call flow for this call is shown below:

 

Similarly, a Skype For Business (O365) client can dial the number of an endpoint off of ITSP and reach out to it over

. The call flow for this call is shown below:

 

O365 Known Issue and Workarounds for CCE

Redeploying the CCE

Re-Initializing of the ASM

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

 

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:

 

Manually Managing the CCE Configuration File

Editing the CCE Configuration File

Exporting and Importing the CCE Configuration File

Updating the CCE Password

Follow these steps if the CCE deployment cannot open the PFX certificate due to a password mismatch.
