Prepare to deploy Azure Communications Gateway

This article guides you through each of the tasks you need to complete before you can start to deploy Azure Communications Gateway. For Operator Connect and Teams Phone Mobile, successful deployments depend on the state of your Operator Connect or Teams Phone Mobile environments.

The following sections describe the information you need to collect and the decisions you need to make prior to deploying Azure Communications Gateway.

Prerequisites

Important

You must be a telecommunications operator to use Azure Communications Gateway.

For Operator Connect or Teams Phone Mobile, you must also have signed an Operator Connect or Teams Phone Mobile agreement with Microsoft. For more information on these programs, see Operator Connect or Teams Phone Mobile.

For Zoom Phone Cloud Peering, you must also have started the onboarding process with Zoom to become a Zoom Phone Cloud Peering provider. For more information on Cloud Peering, see Zoom's Cloud Peering information.

Important

You must fully understand the onboarding process for your chosen communications service and any dependencies introduced by the onboarding process.

Allow sufficient elapsed time for the deployment and onboarding process. For example, you might need wait up to two weeks for a new Azure Communications Gateway resource to be provisioned before you can connect it to your network.

You must own globally routable numbers for two types of testing:

  • Integration testing by your staff during deployment and integration
  • Service verification (continuous call testing) by your chosen communication services

The following table describes how many numbers you need to allocate.

Service Numbers for integration testing Service verification numbers
Operator Connect 1 (minimum) - Production deployments: 6
- Lab deployments: 3
Teams Phone Mobile 1 (minimum) - Production deployments: 6
- Lab deployments: 3
Microsoft Teams Direct Routing 1 (minimum) None (not applicable)
Zoom Phone Cloud Peering 1 (minimum) - US and Canada: 6
- Rest of world: 2
Azure Operator Call Protection Preview 1 (minimum) None (not applicable)

Important

Service verification numbers must be usable throughout the lifetime of your deployment.

If you want to set up a lab deployment, you must have deployed a standard deployment or be about to deploy one. You can't use a lab deployment as a standalone Azure Communications Gateway deployment.

Arrange onboarding

You need a Microsoft onboarding team to deploy Azure Communications Gateway. Azure Communications Gateway includes an onboarding program called Included Benefits. If you're not eligible for Included Benefits or you require more support, discuss your requirements with your Microsoft sales representative.

The Operator Connect and Teams Phone Mobile programs also require an onboarding partner who manages the necessary changes to the Operator Connect or Teams Phone Mobile environments and coordinates with Microsoft Teams on your behalf. The Azure Communications Gateway Included Benefits project team fulfills this role, but you can choose a different onboarding partner to coordinate with Microsoft Teams on your behalf.

Ensure you have a suitable support plan

We strongly recommend that you have a support plan that includes technical support, such as Microsoft Unified Support.

Choose the Azure tenant to use

We recommend that you use an existing Microsoft Entra tenant for Azure Communications Gateway, because using an existing tenant uses your existing identities for fully integrated authentication. If you need to manage identities separately from the rest of your organization, or to set up different permissions for the Number Management Portal for different Azure Communications Gateway resources, create a new dedicated tenant first.

The Operator Connect and Teams Phone Mobile environments inherit identities and configuration permissions from your Microsoft Entra tenant through a Microsoft application called Project Synergy. You must add this application to your Microsoft Entra tenant as part of Connect Azure Communications Gateway to Operator Connect or Teams Phone Mobile (if your tenant does not already contain this application).

Important

For Operator Connect and Teams Phone Mobile, production deployments and lab deployments must connect to the same Microsoft Entra tenant. Microsoft Teams configuration for your tenant shows configuration for your lab deployments and production deployments together.

Get access to Azure Communications Gateway for your Azure subscription

Access to Azure Communications Gateway is restricted. When you've completed the previous steps in this article:

  1. Contact your onboarding team and ask them to enable your subscription. If you don't already have an onboarding team, contact azcog-enablement@microsoft.com with your Azure subscription ID and contact details.
  2. Wait for confirmation that Azure Communications Gateway is enabled before moving on to the next step.

Create a network design

Decide how Azure Communications Gateway should connect to your network. We recommend Microsoft Azure Peering Service Voice (sometimes called MAPS Voice). For more information about your options, see Connectivity for Azure Communications Gateway. If you're planning to use Azure Communications Gateway with VNet injection (preview), complete the prerequisites for deploying Azure Communications Gateway with VNet injection.

For Teams Phone Mobile and Azure Operator Call Protection Preview, you must decide how your network should determine whether a call involves a relevant subscriber and therefore route the call correctly. You can:

  • Use Azure Communications Gateway's integrated Mobile Control Point (MCP).
  • Connect to an on-premises version of Mobile Control Point (MCP) from Metaswitch.
  • Use other routing capabilities in your core network.

For more information on these options for Teams Phone Mobile, see Call control integration for Teams Phone Mobile and Mobile Control Point in Azure Communications Gateway.

The connection to Azure Communications Gateway for Azure Operator Call Protection is over SIPREC. Azure Communications Gateway takes the role of the SIPREC Session Recording Server (SRS). An element in your network, typically a session border controller (SBC), is set up as a SIPREC Session Recording Client (SRC).

If you need to support emergency calls from Microsoft Teams or Zoom clients, read about emergency calling with your chosen communications service:

Important

You must not route emergency calls from your network to Azure Communications Gateway.

Connect your network to Azure

Configure connections between your network and Azure:

Collect basic information for deploying an Azure Communications Gateway

Collect all of the values in the following table for the Azure Communications Gateway resource.

Value Field name(s) in Azure portal
The name of the Azure subscription to use to create an Azure Communications Gateway resource. You must use the same subscription for all resources in your Azure Communications Gateway deployment. Project details: Subscription
The Azure resource group in which to create the Azure Communications Gateway resource. Project details: Resource group
The name for the deployment. This name can contain alphanumeric characters and -. It must be 3-24 characters long. Instance details: Name
The management Azure region: the region in which your monitoring and billing data is processed. We recommend that you select a region near or colocated with the two regions for handling call traffic. Instance details: Region
The type of deployment. Choose from Standard (for production) or Lab. Instance details: SKU
The voice codecs to use between Azure Communications Gateway and your network. We recommend that you only specify any codecs if you have a strong reason to restrict codecs (for example, licensing of specific codecs) and you can't configure your network or endpoints not to offer specific codecs. Restricting codecs can reduce the overall voice quality due to lower-fidelity codecs being selected. Call Handling: Supported codecs
Whether your Azure Communications Gateway resource should handle emergency calls as standard calls or directly route them to the Emergency Routing Service Provider (US only; only for Operator Connect or Teams Phone Mobile). Call Handling: Emergency call handling
A comma-separated list of dial strings used for emergency calls. For Microsoft Teams, specify dial strings as the standard emergency number (for example 999). For Zoom, specify dial strings in the format +<country-code><emergency-number> (for example +44999). (Only for Operator Connect, Teams Phone Mobile and Zoom Phone Cloud Peering). Call Handling: Emergency dial strings
The scope at which the autogenerated domain name label for Azure Communications Gateway is unique. Communications Gateway resources are assigned an autogenerated domain name label that depends on the name of the resource. Selecting Tenant gives a resource with the same name in the same tenant but a different subscription the same label. Selecting Subscription gives a resource with the same name in the same subscription but a different resource group the same label. Selecting Resource Group gives a resource with the same name in the same resource group the same label. Selecting No Re-use means the label doesn't depend on the name, resource group, subscription or tenant. DNS: Auto-generated Domain Name Scope

Decide if you want tags for Azure resources

Resource naming and tagging is useful for resource management. It enables your organization to locate and keep track of resources associated with specific teams or workloads and also enables you to more accurately track the consumption of cloud resources by business area and team.

If you believe tagging would be useful for your organization, design your naming and tagging conventions following the information in the Resource naming and tagging decision guide.
