Connect Azure Communications Gateway to Zoom Phone Cloud Peering

After you deploy Azure Communications Gateway and connect it to your core network, you need to connect it to Zoom.

This article describes how to start connecting Azure Communications Gateway to Zoom Phone Cloud Peering. After you finish the steps in this article, you can set up test users for test calls and prepare for live traffic.

Prerequisites

You must start 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.

You must deploy Azure Communications Gateway.

Using Azure Communications Gateway for Zoom Phone Cloud Peering requires provisioning the details of your customers and the numbers that you assign to them on Azure Communications Gateway. You can do this with Azure Communications Gateway's Provisioning API (preview) or its Number Management Portal (preview). If you're planning to use the Provisioning API:

  • Your organization must integrate with the API
  • You must know the IP addresses or address ranges (in CIDR format) in your network that should be allowed to connect to the Provisioning API

You must allocate "service verification" test numbers for Zoom. Zoom use these numbers for continuous call testing.

  • If you selected the service you're setting up as part of deploying Azure Communications Gateway, you've allocated numbers for the service already.
  • Otherwise, choose the phone numbers now (in E.164 format and including the country code). You need six numbers for the US and Canada or two numbers for the rest of the world.

You must also allocate at least one test number for each service for your own integration testing.

You must know which Zoom Phone Cloud Peering region you need to connect to.

You must have Reader access to the subscription into which Azure Communications Gateway is deployed.

You must be able to contact your Zoom representative.

Enable Zoom Phone Cloud Peering support

Note

If you selected Zoom Phone Cloud Peering when you deployed Azure Communications Gateway, skip this step and go to Ask your onboarding team for the FQDNs and IP addresses for Azure Communications Gateway.

  1. Sign in to the Azure portal.
  2. In the search bar at the top of the page, search for your Communications Gateway resource and select it.
  3. In the side menu bar, find Communications services and select Zoom Phone Cloud Peering to open a page for the service.
  4. On the service's page, select Zoom Phone Cloud Peering settings.
  5. Fill in the fields, selecting Review + create and Create.

    Important

    Do not add the numbers for your own integration testing when you configure test numbers. You will configure numbers for integration testing when you configure test numbers.

  6. Select the Overview page for your resource.
  7. Wait for your resource to be updated. When your resource is ready, the Provisioning Status field on the resource overview changes to "Complete." We recommend that you check in periodically to see if the Provisioning Status field is "Complete." This step might take up to two weeks.

Ask your onboarding team for the FQDNs and IP addresses for Azure Communications Gateway

Before starting this step, check that the Provisioning Status field for your resource is "Complete".

Ask your onboarding team for:

  • All the IP addresses that Azure Communications Gateway could use to send signaling and media to Zoom.
  • The FQDNs (fully qualified domain names) that Zoom should use to contact each Azure Communications Gateway region.

Your Zoom representative needs these values to configure Zoom for Azure Communications Gateway.

Ask your Zoom representative to configure Zoom

Ask your Zoom representative to configure Zoom for Azure Communications Gateway using the IP addresses and FQDNs that you obtained from your onboarding team.

Zoom must:

  • Allowlist traffic from the IP addresses for Azure Communications Gateway.
  • Route calls to the FQDNs for Azure Communications Gateway.

You can choose whether Zoom should use an active-active or active-backup distribution of calls to the Azure Communications Gateway regions.

Tip

Don't provide your Zoom representative with the FQDNs from the Overview page for your Azure Communications Gateway resource. Those FQDNs are for the connection to your networks.
