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.

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.
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).
After you add the domain name, you need to create a user with User Principal Name (UPN), for example, user@0232-40e6-a468-38a329debdd7.teams.didww.com and assign a Teams license. It may take up to 24 hours to fully provision the domain name after it’s added to Domains of your tenant, to create a user with a new name, and to assign a license to the user.
The dialed number pattern ^(\+1[0-9]{10})$ applies to phone numbers in the North American Numbering Plan (NANP), which includes the United States, Canada, and other regions that use the +1 country code. For phone numbers outside NANP, use the appropriate pattern.
Step 5. Add new PSTN usage record (Fig. 13).
