Microsoft Teams Direct Routing¶

Introduction¶

Microsoft Teams Direct Routing allows your organization to use DIDWW as a SIP trunk provider for Voice IN and Voice OUT services within MS Teams. This capability allows customers to enjoy all the benefits and features of the Microsoft Teams phone system while maintaining their existing DIDWW phone numbers, contracts, and competitive calling rates. This user guide introduces MS Teams Direct Routing integration with DIDWW SBC and describes the prerequisites for configuration.

Getting started¶

What you need to get started:

An account at DIDWW.
Voice IN and/or Voice OUT trunks, depending on what service you want to use in MS Teams.
A DIDWW MS Teams SBC domain. Please contact sales@didww.com for more information.
An installed Microsoft Phone System license in MS Teams with enabled Direct Routing. For more information on Microsoft’s licensing requirements, please refer to https://docs.microsoft.com/en-us/microsoftteams/direct-routing-plan#licensing-and-other-requirements.

Domain setup and verification¶

If all prerequisites are met, you will need to activate the domain in the Microsoft admin portal before setting up Direct Routing in Microsoft Teams.

Before you start, make sure you have the Global Administrator rights in your tenant in order to add domains.

Step 1. Login to https://admin.microsoft.com/Adminportal/ and go to Settings –> Domains –> Add Domain.

Add the domain provided by DIDWW (Fig. 1).

Fig. 1. Adding a domain.¶

Step 2. Click on Use this domain and verify it on the following page. Then select Add a TXT record to the domain’s DNS Records. (Fig. 2).

Fig. 2. Verifying the domain on Microsoft Teams.¶

Step 3. Click on Continue and take note of the TXT value. (Fig. 3).

Fig. 3. Information required to verify the domain.¶

Step 4. Share the TXT Value from the MS Teams portal with your DIDWW representative (your account manager or sales@didww.com).

Step 5. After getting a confirmation from your DIDWW representative about the applied changes, go back to Microsoft 365 admin center and click on the Verify button (Fig. 3).

Step 6. On the next page, select More Options , then Skip and do this later and click Continue (Fig. 4).

Note

It is not required to add Microsoft DNS Records as they are only needed for email and instant messaging, but not for Direct Routing.

You will see a screen menu indicating that the setup is complete (Fig. 5).

Domain activation¶

Step 1. After registering a domain, you need to activate it by adding at least one user and assigning an address matching the created domain in the customer tenant(Fig. 6).

Please review Get help with Microsoft 365 or Office 365 domains for more information about adding users in Microsoft 365 or Office 365 organizations.

For example: DIDWW@0232-40e6-a468-38a329debdd7.teams.didww.com

Fig. 15. Assign PSTN usage records with new voice routing policy.¶

The same step can be done using the following PowerShell commands:

New-CsOnlineVoiceRoutingPolicy "DIDWW Route" -OnlinePstnUsages "DIDWW"

Assigning User to the Voice Routing Policy¶

Step 1. Under Users tab, select the preferred user and click Policies. Select Edit Assigned policies and assign DIDWW voice routing policy(Fig. 16).
