What measures indicate quality?

Microsoft provides five individual metrics.

  • Audio degradation average
  • Round trip
  • Packet loss rate
  • Jitter
  • Ratio concealed samples avg

If any of these metrics fall outside of a predetermined threshold value, the audio stream is determined to be suffering from poor quality.

What version of Teams do I need?

To integrate Callroute with Teams you need a Microsoft Phone System licence. This comes standard as part of E5 and Business Voice. For other users, Phone System can be purchased independently. You can see how these plans relate to each other in the diagram below.
