Direct Routing for Microsoft 365

Direct Routing for Microsoft 365

With Direct Routing, you can connect your SBC to almost any telephony trunk or interconnect with third-party Public Switched Telephone Network (PSTN) equipment. Direct Routing enables you to:

  • Use virtually any PSTN trunk with Microsoft Phone System.
  • Configure interoperability between customer-owned telephony equipment, such as a third-party private branch exchange (PBX), analog devices, and Microsoft Phone System.

Microsoft also offers all-in-the-cloud voice solutions, such as Calling Plan. However, a hybrid voice solution might be best for your organization if:

  • Microsoft Calling Plan is not available in your country.
  • Your organization requires connection to third-party analog devices, call centers, and so on.
  • Your organization has an existing contract with a PSTN carrier.

CUSTOMER DEPLOYED SCENARIO. 

You are already familiar with our initial approach to deployment. This scenario has 3 key elements: (1) Office 365 with Phone System enabled, (2) Session Border Controllers (SBC) from our certified partners such as AudioCodes and (3) trunks from your voice provider. Customers have been previewing this scenario since May. For customers who want to manage the infrastructure on-premises this will be their optimal choice. 

PARTNER HOSTED SCENARIOS.  Back in May 2018, we also began working with providers around the world on a second scenario to ensure that customers who wanted a hosted architecture would have options. This can mean hosted SBCs, additional management capabilities, and other services. We encourage you to reach out to this first set of providers who tested Direct Routing in their environments – BezeQ InternationalBTCellipNuwave CommunicationsOrange Business ServicesSwisscomTATATelekom Deutschland, Telenor, Thinktel, and West to learn more about their offerings. As we go forward, we expect more companies to offer solutions and services with Direct Routing to our joint customers.

Direct Routing also supports users who have the additional license for the Microsoft Calling Plan. For more information, see Phone System and Calling Plans.

With Direct Routing, when users participate in a scheduled conference, the dial-in number is provided by Microsoft Audio Conferencing service, which requires proper licensing. When dialing out, the Microsoft Audio Conferencing service places the call using online calling capabilities, which requires proper licensing. (Note that dialing out does not route through Direct Routing.) For more information, see Online Meetings with Teams.

Direct Routing allows customers to choose their telecom provider to enable their users to make and receive calls in Teams. If your country is supported by Teams and Phone System you can start planning and deploying Direct Routing in your organization today. Direct Routing and Calling Plans are now your 2 choices for dial tone in Microsoft Teams.

There are two primary approaches to deploying Direct Routing for you to consider.

 

Planning your deployment of Direct Routing is key to a successful implementation. This article describes infrastructure and licensing requirements and provides information about SBC connectivity:
