M5 Technologies’ line of SBCs are now certified for Microsoft Teams Direct Routing


M5 Technologies is proud to announce that the Mediatrix Sentinel Session Border Controller (SBC) series is officially certified for Microsoft Teams Direct Routing.

Available in a variety of combinations, from the Sentinel 100 Pure SBC to the Sentinel 400 multiservice enterprise platform with 8 telephony modules (E1/T1, FXS, FXO, ISDN and BRI), our entire line of SBCs run the same certified DGW version 48.x firmware.


“This is yet another step in our unified effort to enable even more people all around the world to have a fantastic work and collaboration experience,” says Filipp Seljanko, Senior Program Manager, Real-Time Communications, PSTN Direct Routing at Microsoft.


Microsoft Teams is the standard unified collaboration and communication tool included with Office 365 that provides chat, meetings, files, apps, and calls. Available for Windows, Mac, Android, iOS and web platforms, it can also connect to traditional telephony with the Direct Routing feature and a certified SBC.

Connect with Anyone, Anywhere

Many companies are starting to deploy Teams and Office 365 to desktops and smartphones. While ideal for the typical office worker, this does not cover everyone in the company and can be challenging in some environments.

For example, retail and factory workers often do not have computers or cell phones at work. Wireless coverage may be spotty or unavailable in locations such as warehouses, hospitals, and elevators. However, plain old telephones are ubiquitous. 

Direct Routing lets you integrate any telephony equipment with Teams, including Key systems, DECT phones, intercoms, paging equipment, emergency or elevator phones, door panels, etc.

Continue using  your existing equipment and phone contracts, and save on licensing

With Direct Routing, you don’t need an expensive Microsoft Calling Plan License for each user, nor are you limited to the countries for which the Microsoft Voice feature. Use the telephony provider of your choice, either via SIP or the traditional PSTN network.

Keep your existing contracts and phone numbers. Keep your licensing costs to a minimum by only assigning the “Microsoft 365 Business Voice Without Calling Plan” to the users who need it.

100% certified, tested and supported

The certification process is the culmination of over a year of hard work. After extensive collaboration between customers, our Technical Assistance Center team and our R&D engineers, our Sentinel SBC was sent to TekVizion, an independent accredited test lab for two rounds of testing. After passing all the tests, our DGW 48.x firmware was officially certified by Microsoft for the entire Mediatrix Sentinel series.


With a Mediatrix Sentinel Session Border Controller, organizations can now connect Microsoft Teams to their business-class telephony solution of choice, and be assured of the highest standard of quality, excellence in support and lowest ownership cost – the core values of M5 Technologies.
