Access power and flexibility

  • Make and receive external calls

    Direct Routing allows Microsoft Teams to make and receive external calls within the platform. It optimizes Microsoft licensing to help enterprises make massive cost savings by empowering calling for individual users rather than the entire organization. Voice calling is also available through Teams for analog devices, lobby phones, and other locations where end users might not have access to the app. 

  • Route calls from the Microsoft Phone System

    Direct Routing uses Session Border Controllers (SBCs) and SIP Trunk platforms to link the Public Switched Telephone Network (PSTN) to Teams. By selecting a provider like Sinch, with 99.999% uptime, you can rest assured of high reliability and availability — especially essential for businesses operating 24x7.   

  • An integrated call experience

    Best suited for businesses with complex needs, you can integrate calling between Teams users and other business-critical functions like remote teams and call centers. Plus, take advantage of additional SIP Trunk features like SIP-enabled phones, number porting, and international calling. 

  • Reliable emergency calling

    We’re one of the select few providers offering secure, seamless E911 calling directly through Microsoft Teams. So, no matter if your workforce is onsite or remote, you can be confident our 911 nomadic location management and precision routing will provide a seamless connection to emergency services.
