Before this release, if your CCE auto-updates to CCE 2.1.0:

  • To rerun the step “Transfer Credential from SBC”, it will require 7.0.1.

For details on troubleshooting, see Troubleshooting Cloud Connector.

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.

 

Figure : 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.
