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
Before You Start
CCE Deployment Scenarios
Scenario 1 and Scenario 2 are covered in Configuring the SBC Edge for a Single CCE. This document contains steps for Scenario 3 and Scenario 4.
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. Latest System Release SBC Firmware and SbcComms Firmware Important!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"). Microsoft Cloud Connector Edition image on ASM recovery partition.
We recommend deploying both Appliances on the same subnet with a resilient connection.
For the purposes of this document, the CCE is deployed in the following network:

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.
Any changes to the Configure CCE tab requires the CCE to be redeployed.
Step | Action |
---|---|
1 | Login to the WebUI of the SBC Edge. |
2 | Navigate to Tasks > Office 365 Cloud Connector Edition> Setup. |
3 | Click the Configure CCE tab. |
4 | Configure all necessary information and then click OK. TLS 1.2 is supported; the following fields are required to configure TLS:
If TLS is configured as the Primary SBC Transport Protocol, you must run the Synchronize CCE/SBC CA Certificate task to allow a successful TLS handshake between CCE and SBC Edge. However, if TCP is configured as the Primary SBC Transport Protocol the Synchronize CCE/SBC CA Certificate task is not mandatory. See Managing Cloud Connector Edition Private Certificates. Configuring the ASM – CCE-1 Configuring the ASM – CCE-2 Note: Enter the ASM's IP address in the HA Master IP Address field. The Slave uses the same root certification as the Master, and this location contains the shared folder that contains the Root CA of the Master. |
5 | To increase Fast Failover (which shortens the time where certain ported numbers have a long delay from ITSP PSTN provider) configure Trunk Information: Refer Support. Indicates whether Gateways support Refer for a Call Transfer scenario. Valid entries: Enable (the Gateway(s) supports Refer which can handle call transfer) or Disable (the Gateway does not support Refer and the Mediation Server handles call transfer). Fast Failover Timer. Determines whether outbound calls that are not answered by the gateway within ten seconds will be routed to the next available trunk; if there are no additional trunks, the call will automatically be dropped. Valid entries: Enable or Disable. Forward Call History. Indicates whether call history information is forwarded through the trunk. Valid entries: Enable or Disable. Forward PAI. Indicates whether the P-Asserted-Identity (PAI) header will be forwarded along with the call. Valid entries: Enable or Disable. |
6 | After receiving the activity status as successfully completed, click the Prepare CCE tab to continue. |
You must verify (and possibly correct) the CCE Configuration INI File after configuring the CCE.
When deploying a High Availability (HA) systems, it is important to have Management IP Prefix unique on each HA system. For instance, if your HA Master CCE system has 192.168.213.x as the Management IP Prefix, you need to be sure to configure this attribute differently on HA Slave system. While doing this, also make sure that subnet that you are defining in this field does not conflict in your IP infrastructure.
Perform these steps on both SBC Edge systems.
Follow these steps to verify and correct values in the CCE Configuration INI File.
