Discover why configuring the SIP Gateway provisioning server URL is the critical first step when adding SIP devices to Microsoft Teams for the MS-721 certification exam.

Question

You have Microsoft Teams Phone deployment with SIP Gateway.

You acquire 10 SIP devices.

You need to add the devices to Teams.

What should you do first?

Select only one answer.

A. Configure a Conditional Access policy for the devices.
B. Configure a device tag.
C. Configure an Enhanced encryption policy.
D. Configure the SIP Gateway provisioning server URL.

Answer

To integrate SIP devices into a Microsoft Teams Phone deployment via SIP Gateway, the first step is to configure the SIP Gateway provisioning server URL (Option D).

D. Configure the SIP Gateway provisioning server URL.

Explanation

For each SIP device, set one of the following SIP Gateway provisioning server URLs:

  • EMEA: http://emea.ipp.sdg.teams.microsoft.com
  • Americas: http://noam.ipp.sdg.teams.microsoft.com
  • APAC: http://apac.ipp.sdg.teams.microsoft.com

Add SIP devices to a Teams deployment by configuring the above SIP Gateway provisioning server URL on a DHCP server or manually. Successfully provisioned SIP phones will display the Teams logo and a soft button for sign-in.

Microsoft Teams SIP Gateway requires SIP devices to connect to regional provisioning servers for onboarding. Here’s the breakdown:

Provisioning Server Configuration

  • The SIP Gateway provisioning server URL (e.g., http://noam.ipp.sdg.teams.microsoft.com for the Americas) must be set in your DHCP server or manually on each device. This ensures devices retrieve configuration files from Microsoft’s servers.
  • Without this URL, SIP devices cannot communicate with Teams or complete registration.

Why Other Options Are Incorrect

(A) Conditional Access Policies: These manage user access but are unrelated to device provisioning.

(B) Device Tags: Used for grouping devices post-provisioning, not for initial setup.

(C) Enhanced Encryption Policies: Apply to data security, not device enrollment.

Post-Configuration Steps

After setting the URL:

  1. Add MAC addresses in the Teams Admin Center under SIP Devices > Actions > Provision Devices.
  2. Generate verification codes and complete device registration.

Example Workflow

1. Configure DHCP Option 160 (Americas):

`http://noam.ipp.sdg.teams.microsoft.com`

2. Reboot SIP devices to auto-provision.

3. Enroll MAC addresses in Teams Admin Center[6][24].

By prioritizing the provisioning URL, you ensure SIP devices connect to Teams’ infrastructure, enabling subsequent enrollment and policy management.
