Cisco WebEx, which is also popular in the enterprise, allows users to see up to 25 participants. Hangouts in G Suite supports up to 25 people on a video call.
"The Microsoft Teams roadmap does include increasing the number of people viewable during a Teams video call to 49," the report quoted a Microsoft spokesperson as saying.
