Azure Communication Services

This guide connects Azure Communication Services to Live Hub. Complete the following steps:

  1. Create a SIP connection in Live Hub
  2. Configure a Direct Routing domain in your Azure Communication Services account
  3. Verify the Live Hub domain
  4. Configure the Direct Routing SBC in your Azure Communication Services account

Create a SIP connection in Live Hub

To create the SIP connection that represents your Azure Communication Services account:

  1. Log in to Live Hub.

  2. In the Navigation pane, select SIP connections, and then click Add new SIP connection.

      • In the 'Name' field, enter a unique SIP connection name (for example, ACS).
      • From the 'Provider type' drop-down list, select UC Platform.
      • From the 'Provider' drop-down list, select Azure Communication Services.

  4. Select the Incoming tab:

    • Select the 'FQDN (Request-URI)' check box.
    • Copy the 'SIP connection FQDN' value that appears. You need it when you configure Direct Routing in your Azure Communication Services account.

    The Domains tab

  5. Calculate the Live Hub base domain by removing the first element from the 'SIP connection FQDN'. For example, if the FQDN is fjoigfgmeuol.sip1-region1.audiocodes.io, the Live Hub base domain is sip1-region1.audiocodes.io.

  6. Enter the Live Hub base domain, and then click Confirm.

    Adding a custom domain

  7. Click Add, and then wait for the domain to be added.
