As a Gold Communications Partner, Ribbon works with Microsoft to certify our session border controller (SBC) portfolio for Microsoft Phone System Direct Routing and Skype for Business. Changes to the Phone System are tested with Ribbon before their general availability. This collaboration leads to official support from Microsoft. Our SBCs connect Microsoft Teams to SIP trunks, providing enterprises with a choice when purchasing a calling plan.
Ribbon boasts the largest portfolio of SBCs certified for Direct Routing for Microsoft Teams and Skype for Business. This includes both physical network appliances and virtual, software-only, SBCs. Our SBCs have been found in some of the world's largest carrier networks for decades. Our physical SBCs scale to 150,000 SIP sessions and our Software Edition (SWe) has no defined limit. Our SBCs can be deployed in a multi-tenant environment, allowing you to take advantage of economies of scale. The rare combination of session density and Microsoft certification make Ribbon the perfect vendor to include in SIP trunking offerings for Microsoft customers.
