About Mitel CloudLink 1

CloudLink is Mitel’s next generation Cloud platform that enables Mitel to build and deliveradvanced applications quickly and enhances select on-premises solutions with feature-richcloud-based capabilities.

Some of the primary services provided by the CloudLink Platform include Identity and AccessManagement (IAM), chat, presence, notifications, workflow, media services, and ShortMessage Service (SMS).

The CloudLink Platform is built on the Amazon Web Services (AWS) cloud computingplatform, which provides enterprise-level uptime and stability, multi-layered security, and dataprotection.

CloudLink Platform 1

CloudLink Administration 2This chapter contains the following sections:

• CloudLink Policy• CloudLink Portals Available through MiAccess• CloudLink Accounts

Mitel CloudLink applications are administered through appropriate CloudLink portalsavailable on the Mitel MiAccess Portal. A valid Mitel Account is required to login. CloudLinkportals are designed to deploy specific applications or services. Portal functionality is notinterchangeable and should be used only to administer the deployed application or theservice used. CloudLink portals are available only through Mitel MiAccess and after anapplication or service is released in each country or region.

2.1 CloudLink Policy

To enable personnel to log in to the different CloudLink portals via Mitel MiAccess, theappropriate CloudLink 'policy' must be implemented for individual users (or to userswho are part of a bundle) by a Partner Administrator through the Mitel MiAccess usermanagement portal. To enable the policy, raise a request in MiAccess Help.

2.2 CloudLink Portals Available through MiAccess

• CloudLink Gateway Portal

Provides information about configuring, managing, and using the CloudLink Gatewayto enable communications between an on-premises MiVoice Office PBX and cloud-based Mitel applications.

• CloudLink Accounts Console

Provides information about configuring and managing CloudLink accounts for Partnersand customers. Any entity that wants to use Mitel cloud applications built on CloudLinkmust have an account created in this portal. For certain applications such as MiCollab,the user accounts are synchronized with the CloudLink account from the MiCollabservers.

CloudLink Platform 2

2.3 CloudLink Accounts

Mitel CloudLink applications require a customer account on the CloudLink Platform.CloudLink customer accounts are created and managed through a specific CloudLinkportal.

Mitel Partners will manage multiple CloudLink accounts for their own business and fortheir customers as they deploy CloudLink applications. All CloudLink accounts createdunder a Partner’s MiAccess Account will be visible from the listed CloudLink portals,regardless of where the application is deployed.

Note:When a Mitel Partner logs in to the Accounts Console via the Mitel MiAccess Portalfor the first time, a default Partner Account is created and assigned to that Partner inCloudLink Accounts console and a new user is created for the Partner using the MitelMiAccess User credentials. The Partner Account maintains the login details of all thePartners. The Partner Account and the Partner in an account cannot be deleted.

Mitel Partners must perform CloudLink account maintenance through the appropriateCloudLink portal for each application or service used by that account. For example, if theaccount was created using the CloudLink Accounts Portal, that same portal should beused to perform account maintenance.

System Requirements 3

The following articles describes the minimum system requirements for deploying a CloudLinkapplication.

Bandwidth Requirements

CloudLink applications work with IPv4 and IPv6 networks. A CloudLink mobile application willconnect to the user’s preferred Wi-Fi network if that network is available. If the preferred Wi-Fi network is not available, the application will connect to an LTE network. The application canuse 2G, 3G, 4G, and 4G LTE networks but the voice quality and the connectivity depend onthe network strength.

Note:CloudLink application embedded SIP soft phones should not be statically provisionedwith an address on the local network. When a customer’s network has active IPv6 routersthey must have some form of automatic distribution of addresses to a mobile community(SLAAC or DHCPv6).

The following table lists the recommended bandwidths for a single CloudLink application call.

Network Kbps Codec

Wi-Fi 220 G.711 and Opus

3G/4G 110 G.711

If bandwidth is insufficient, the web or mobile application user might encounter voice qualitydegradation, slow response, service interruption, and loss of service.

System Requirements

Bandwidth Optimization

Bandwidth Optimization is designed to reduce internet bandwidth usage for CloudLink callswhen callers are operating in the same network as the CloudLink Gateway and MiVoice Office400. When Bandwidth Optimization is enabled, the media (that consumes the bandwidth)between users in the same network will not be routed to the Mitel CloudLink Platform.

Pre-requisites

To optimize bandwidth utilization for users in a customer account:

• The Mitel Partner or an Account Admin of the customer account must enable BandwidthOptimization for the account. For more information about how to enable BandwidthOptimization for a customer account, see the section Bandwidth Optimization in CustomerAccount Information.

• Mitel One web application / MiVoice Office Mobile Application (MOMA) / MiVoice OfficeWeb Application (MOWA), CloudLink Gateway, and the MiVoice 400 PBX (MIVO400) mustbe on the same network.

• The company’s internal network must fully route the voice path between the CloudLinkGateway and Mitel One/MOMA/MOWA.

• Indirect switching must not be enabled on MIVO400.

Supported Use Cases

Bandwidth Optimization is supported for:

• Mitel One/MOMA/MOWA to Mitel One/MOMA/MOWA calls• Mitel One/MOMA/MOWA to other phone endpoints on MIVO400

11 CloudLink Platform

System Requirements

• Mitel One/MOMA/MOWA to trunk calls when the trunks are on MIVO400

When a call is placed, the media is routed to the Mitel CloudLink Platform and then to theCloudLink Gateway. After the call is connected, the media is optimized immediately or assoon as the signaling allows it to be and then the call is routed directly to the CloudLinkGateway, bypassing the Mitel CloudLink Platform, provided that the callers are in the samenetwork, bandwidth optimization is enabled, and the pre-requisites are met.

When you use the call features on Mitel One/MOMA/MOWA, such as place a call, transfer,retrieve, swap, or add a call, Bandwidth Optimization occurs only when the pre-requisites foroptimization are met; the call flow will be alternately routed between the CloudLink Platformand the Mitel endpoints on the customer premises.

The following table lists the bandwidth consumed by Mitel One, MOMA and MOWA calls.

Call Flow Bandwidth Optimization Off Bandwidth Optimization On

Mitel One/MOMA/MOWA to Mitel One/MOMA/MOWA on WiFi

220 Kbps 60 Kbps

Mitel One/MOWA to 6900 on LAN 110 Kbps 30 Kbps

Mitel One/MOWA to Mitel One/MOWA on LAN

220 Kbps 60 Kbps

MOMA to MOMA on GSM 110 Kbps 110 Kbps

Bandwidth Optimization Call Flow Diagrams

The following call flow diagrams provide visual representations of the media path whenBandwidth Optimization is disabled and enabled, respectively.

Call Flow when Bandwidth Optimization is disabled

When Bandwidth Optimization is disabled, calls between Mitel One/MOMA/MOWA usersor between Mitel One/MOMA/MOWA users and PSTN/Trunk users are routed through theinternet router to the CloudLink Platform, and then to the CloudLink Gateway. The bandwidthconsumed at the internet access connection is that for two concurrent calls.

Figure 12: Call flow when Bandwidth Optimization is disabled

CloudLink Platform 12

System Requirements

Call Flow when Bandwidth Optimization is enabled

When Bandwidth Optimization is enabled, calls between Mitel One/MOMA/MOWA users orbetween Mitel One/MOMA/MOWA users and PSTN/Trunk users, in the same network, arerouted only through the CloudLink Gateway. Because call flows are not routed through theinternet router to the Mitel CloudLink Platform, there is minimal bandwidth consumed at theinternet access point, with only signaling maintained throughout the call.

13 CloudLink Platform

Restrictions

Bandwidth Optimization will not work when:

• the users are connected to an external network (any network other than the company'sinternal network) or are using LTE.

• Mitel One/MOMA/MOWA, CloudLink Gateway, and MIVO400 are on different networks.• MIVO400 and CloudLink Gateway are deployed in a separate data center by a hosted

service provider.

CloudLink Applications PartnerSupport Process 5

The following partner support process is applicable for Mitel One web application, MiVoiceOffice Mobile Application (MOMA), MiVoice Office Web Application (MOWA), MiTeamMeetings, and CloudLink Chat.

All these products are part of a parent product. Tickets with support should be opened on theparent product as per normal procedure in the region where you reside. For instance, MitelOne, MOMA and MOWA tickets would be opened with your regional support team through thenormal process used for MiVoice Office 400. For MiTeam Meetings hosted in MiCollab, ticketswould be opened under the MiCollab product. Connect/Teamwork tickets would be openedthrough Salesforce as part of the parent product.

All these products can send reports and logs. These reports and logs are provided to Miteland at the same time, an email is sent to the configured Support Contacts in the CloudLinkAccounts Console or in the case of Mitel One/MOMA/MOWA the Maintainer and OnsiteAdmin contacts in the CloudLink Gateway portal. The email is sent each time a user sendsa report which contains information about the problem encountered when it was reported. Itis the Partner’s responsibility to handle these reports and if needed, create tickets with Mitel.Mitel reviews the reports for identifying platform-specific operational and performance trends.Mitel will not reach out to the partner or the end customer directly.
