Microsoft Teams Network Assessment Tool

1. Network performance – Test the connection to a Microsoft Teams relay by streaming packets to the nearest edge site and back for a configurable amount of time. The tool collects and outputs loss, jitter, and round trip time during this packet exchange. The results from set of test calls can be analyzed to determine if it meets the media quality and performance targets described here: https://support.office.com/en-us/article/Media-Quality-and-Network-Connectivity-Performance-in-Skype-for-Business-Online-5fe3e01b-34cf-44e0-b897-b0b2a83f0917 . These targets and testing apply for Microsoft Teams calls only.
2. Network connectivity – Verify network and network elements between the test location and the Microsoft Network are correctly configured to enable communication to the IP addresses and ports needed for Microsoft Teams calls. The addresses and ports are described here: https://support.office.com/en-us/article/Office-365-URLs-and-IP-address-ranges-8548a211-3fe7-47cb-abb1-355ea5aa88a2#bkmk_teams.
