AT&T - Direct Routing for Teams with AT&T

by AT&T

Customers use the AT&T Voice Network to make and receive off-net calls within Microsoft Teams

Direct Routing for Teams with AT&T allows you to empower your workforce to collaborate anytime, anyplace with SIP trunking, SBC-as-a-Service, and professional services from AT&T.  It provides off-net voice calling from AT&T with Microsoft Teams.

The Challenge;

  • You need high-quality voice and collaboration in and out of the organization,  but may not want to manage additional equipment or connections to the public switched network.
  • Enterprises frequently find their IT and network architecture needs to be redesigned to achieve the Microsoft Teams experience required of a sophisticated and often remote workforce.
  • With a mix of equipment, dialing plans, and device, the integration and migration to voice calling with Microsoft Teams can be complex and confusing.


  • High-quality Teams voice calling while still allowing for connection to existing PBX and analog SIP gateways to support analog telephones, fax machines and paging
  • Use a Session Border Controller (SBC) hosted and managed by AT&T…or use your own.    And for Customers currently using AT&T IP Flexible Reach, there is no requirement to port telephone numbers.
  • Integration expertise from AT&T for pre-sales, design, consulting, and support is available to get you up and running quickly.
