Microsoft Teams Direct Routing

Author: Liz Fieno

In 2017, Microsoft released Teams as an integration with their Office 365 subscription productivity suite. Teams is Microsoft’s Unified Communications-as-a-Service (UCaaS) platform and has replaced Skype for Business Online, allowing users to collaborate via chat, video conference, and calling.

What is Microsoft Teams Direct Routing?

Direct Routing allows an organization to access the PSTN (Public Switched Telephone Network) from Microsoft Teams so users to make and receive phone calls. In order to connect to the PSTN from teams, you must enable Microsoft Phone System, its native PBX functionality.

Microsoft Phone System is included with certain licenses like E5, but can also be purchased as an add-on to an E3 license. In order to ensure incoming and outgoing calls are passed through the Microsoft Teams client and delivered to your end-users, you’ll need a Microsoft-certified SBC (Session Border Controller) as well as a provider for both your SIP trunking and Dynamic E911 Services.

The benefits of Teams Direct Routing

One of the most attractive things about Direct Routing is the pay-for-what-you-use model that generally comes with SIP trunking. The cost of Direct Routing depends on your individual inputs, such as who your SIP trunking provider is, what usage model you’re set up for, who your E911 provider is, what E911 services you require, who your SBC vendor is, and what option (hosted, on-prem, etc) you choose.

When an organization decides to use Teams for PSTN access and obtains the proper license with Microsoft Phone System, they actually have three options: Direct Routing, Operator Connect, and Microsoft’s own Calling Plans. Microsoft Calling Plans, powered by Bandwidth, is a seat-based model that comes with a list of line features.

What are Microsoft Teams Calling Plans?

Pricing and features for Teams Calling Plans are dependent upon an organization’s Office 365 license level, and can also vary in both price and availability by International Region.

At the time of writing, Microsoft lists Calling Plan pricing at around $12 per license for domestic calling and $24 for international plans with associated minute caps under two headings: 

  • Domestic: 3,000 domestic minutes in the US and Puerto Rico and 1,200 domestic minutes in the UK 
  • International: 3,000 domestic minutes in the US and Puerto Rico, and 1,200 domestic minutes in the UK; 600 international minutes. (Source)

Additional domestic or international minutes may be purchased in the form of Communication Credits, which can be purchased as necessary at any time. Phone numbers are included in Calling Plans, but existing numbers can be ported over from a current carrier.

Calling Plans vs. Direct Routing

Organizations tend to use Calling Plans because of the simplified telecom purchasing,  easy-to-understand per-seat pricing, and the ease of turning up new workstations. It’s important to note that the trade-off for ease of deployment generally results in greater recurring cost in the form of the per-seat cost model, and in limitations on domestic and international minutes. 

The other option, Direct Routing, tends to appeal to organizations that want to maintain legacy routing and features/functionality of on-prem equipment while gaining more control, scalability, and cost-efficiency. Microsoft Teams Direct Routing allows companies to only pay for what they use. There’s also no need to port your existing numbers over to Microsoft’s Calling Plans, so keeping that number ownership with a carrier also tends to be a favorable option for larger enterprises. 

How to migrate to Teams Direct Routing

Migrating to a cloud-based UCaaS system like Microsoft Teams presents a whole host of challenges.

How does Direct Routing work?

In simple terms, here’s how to deploy Direct Routing:

Remember, you need to set up a Dynamic E911 solution alongside Direct Routing. See below for more information.

Dynamic E911 for Microsoft Teams Direct Routing

Microsoft Teams leverages dynamic E911 capabilities which provide public safety with user location that is determined at the time of the emergency call. With Teams, organizations can also specify more granular location information such as a floor, suite, quadrant, or room (as well as civic address) to public safety, setting the stage for faster, more reliable emergency outcomes.

Dynamic E911 for Microsoft Teams Direct Routing supports non-fixed VoIP dispatchable location requirements that are now part of many state E911 regulations as well as RAY BAUM’s Act. Teams also includes a notifications feature that can be enabled to alert designated personnel such as a security team of a 911 call. This requirement is now part of Kari’s Law.

While much of the 911 configuration and location management is performed within Microsoft Teams, Bandwidth provides the essential interconnectivity to public safety. We route the calls to the appropriate public safety answering point (PSAP) and make the location information available to the 911 call taker for emergency response.
