When we say we’re native, we mean it.

Every action and voice experience stays within Teams. Other
solutions promote being native to Teams, however, typically the voice experience will exit Teams and enter a 3rd party application.

  • Native connectivity and QoS attributes – It’s a true Teams call
  • Native interaction with other Teams users (incl. transfer etc)
  • Native ability to move devices within a Teams call
  • Native Presence
