# What should I do if telephony in MS Teams is restricted?

This article explains the **procedure** for **various error messages** in the **in connection with MS Teams** . A uniform approach is often easier to implement than creating different scenarios with separate case distinctions for each situation. If telephony in MS Teams is restricted, please follow these steps:

{% stepper %}
{% step %}
**Check online integration**

*Affects both inbound and outbound telephony.* First, you should check the registered devices on the affected extension of the user.

* To do this, log in to **sipgate** and navigate to **user**
* Click on the affected extension and check under **Logged-in devices**whether devices are registered there.
* Also check by clicking on the **gear icon** which devices are listed. More information can be found in the video [Check logged-in devices](https://www.loom.com/share/fb84b43c8a524b1fa5e99bc2ea216205?sid=f226221f-5bc4-4d4e-8f48-b4ea05ecd86d)
* If no devices are registered or if the logged-in devices **NOT** "**GILAWA DR-SBC GW"** is listed:
  * Please write to <support-ms-teams@sipgate.de>that the MS Teams integration is not online.
  * Please include the affected user, your customer number, and a callback number, preferably a mobile number.
  * Wait for a response.
  * If that worked, continue with the next step.
    {% endstep %}

{% step %}
**Match phone numbers**

*Affects both inbound and outbound telephony.*

* Match the **Phone numbers** of the user in the **sipgate profile** with the user's phone number in your **Office tenant** . You can also check the required license in the Office tenant directly.
* Also check the numbers for **typos,** because a connection can only be established with identical phone numbers.
* More information can be found in the video [Match phone numbers](https://www.loom.com/share/50a7f0ea584d4bcd8e4cf664bf79237b?sid=65ec6f51-746f-4859-b53b-4a64f9e7a784)
  {% endstep %}

{% step %}
**Check routing policy**

*Affects outbound telephony.*

* Open the **User profile** in the **MS Teams Admin Center**
* Select **Policies**
* Check which VoIP routing policy is set.

  <div data-gb-custom-block data-tag="hint" data-style="info" class="hint hint-info"><p>Note: For the integration with sipgate, it should also be named this way</p></div>

  {% endstep %}

{% step %}
**Exclude call forwarding**

*Affects inbound telephony.*

* Check the **Forwarding settings** of the user in the **sipgate portal** More information can be found in the article [**How do I set up call forwarding?**](https://help.sipgate.de/hc/de/articles/360019990558-Wie-stelle-ich-Weiterleitungen-ein)
* Check the **Forwarding settings** of the user in the **Office tenant** More information can be found in the video [Check forwarding in the MS Teams Admin Center](https://www.loom.com/share/2cba94b146024f308c742d60b1f2a030?sid=90f014ba-1a58-4002-a85b-479299de6e69)
