abacusVoice - Software Phone

Powered by Microsoft Teams

With a software phone app, you no longer need to be tied to a desk phone or forward calls to your mobile phone. Use this “lighter” version of a desk phone to expand your mobility, while still being able to make and receive calls directly from your work number, from anywhere.

  • EASY TO LEARN: Calling experience is integrated into the popular Microsoft Teams applications.
  • DEVICE AGNOSTIC: The Teams app can be installed on Windows or Apple workstations, in addition to Android or iOS mobile devices.
  • EASY-TO-DEPLOY: Abacus engineers configure the back end and your users simply download the Teams  app onto their selected devices, log in with their Abacus credentials and are ready to start using the app immediately.
  • EXPANDS MOBILITY: Your work number is now wherever you are, whether working from home, another location, while walking your dog or traveling between meetings.
  • CREATES CONVENIENCE: Eliminates the need to forward your work number to your mobile device when not in the office or when leaving your desk.
  • ENSURES CONSISTENCY: When making outbound calls, the recipients caller ID will show your work number, not your mobile number.
