Infographic – Microsoft’s Journey into Voice
View an infographic timeline of Microsoft's journey into voice, from where they started to where they are now. Teams is Microsoft’s fastest-growing business application of all time! Recently announcing 280M Monthly Active Users, Microsoft Teams is leading the Gartner Magic Quadrant for Unified Communications as a Service. From a Teams Phone perspective, 80 million are active monthly users but only 10 – 20% are currently enabled for PSTN calling. This number is expected to double over the next three to four years, posing a huge window of opportunity for Carriers and Service Providers.
