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. 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:
In this best practice the router/firewall is configured with the following rules:
Make sure that CCE FQDN is resolving to the SBC Edge Public IP address. To do so, login to your DNS server and create the relevant entries.
Update the SBC Edge firmware to the latest release version.
Ribbon recommends starting with a clean and empty configuration.
When configuring a secondary SBC Edge in your environment, make sure to have the secondarySBC Edge network interface is configured accordingly to be able to reach out to CCE's internal/corporate network.
If your ASM has been used previously, reinitialize it following the steps in Re-Initializing the ASM.
Confirm that the ASM is ready to deploy the CCE by following these steps.

Perform these steps on both SBC Edge systems.
Step | Action |
---|---|
1 | Login to the WebUI of each SBC Edge. |
2 | Navigate to Tasks > Office 365 Cloud Connector Edition> Setup. |
3 | Click the ASM Config tab and configure/verify the Network and IP settings of your ASM as shown below. |
4 | From the Remote Desktop Enabled drop down list, select Yes (to enable Remote Desktop) or No (to disable Remote Desktop). |
5 | From the Windows Firewall Enabled drop down list, select Yes (to enable Windows Firewall) or No (to disable Windows Firewall). |
6 | From the Proxy Enabled drop down list, Enables use of the Proxy Server on the ASM. Select from the drop down list: Yes (enables Proxy Server on the ASM) or No (disables Proxy Server). |
7 | From the Proxy Address drop down list, select Yes (to enable the IP address for the Proxy Server in IPv4 format). This field is available only when Proxy Enabled is set to Yes. |
8 | From the Proxy Port drop down list, select Yes (to enable the port in which the Proxy Server connects). Valid entry: Valid entry: 1 - 65000. This field is available only when Proxy Enabled is set to Yes. |
9 | Configure/verify the Network and IP settings of your ASM. |
10 | Click Apply. After receiving the activity status as successfully completed, click the Generate CSR tab. |
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.
Perform these steps on only one of theSBC Edge systems.
Step | Action |
---|---|
1 | Login to the WebUI of one of the SBC Edge. |
2 | Navigate to Tasks > Office 365 Cloud Connector Edition> Setup. |
3 | Click the Generate CSR tab. |
4 | Generate the CSR as shown below with following information. Note: This example uses aepsite1.sonusms01.com and sip.sonusms01.com as common name and SAN. To ensure creating a valid CSR for Cloud Connector Edition usage, please see the section "Certificate requirements" on https://technet.microsoft.com/en-us/library/mt605227.aspx. |
Perform these steps on both SBC Edge systems.
Step | Action |
---|---|
1 | Login to the WebUI of the SBC Edge. |
2 | Navigate to Tasks > Office 365 Cloud Connector Edition and click the CCE Public Certificate tab. |
3 | On SBC-1, click the Action drop-down list and select the appropriate option:
|
4 | On SBC-2, click the Action drop-down list and select the appropriate option:
|
5 | After receiving the activity status as successfully completed, click on Configure CCE tab. |
Perform these steps on both SBC Edge systems.
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. 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.
