Learning objectives - Do bandwidth planning before you deploy Microsoft Teams and test each network segment to verify if it meets the Media Networking Requirements. After the deployment, continuously monitor with the Call Quality Dashboard (CQD)
Just because Teams works, does not mean it works right. Teams is built to overcome network issues by using TCP for media or relays for example, but this is not the optimal way to use the product.
Often smaller organizations (<250 users) will not deploy QoS, but for larger campuses this is essential. QoS will not help if the bandwidth is oversubscribed, so please do Bandwidth Planning with the FastTrack tool. In the future additional Bandwidth controls and QoS controls will be added to the Teams Admin GUI.
Get Office 365 traffic to Office 365 ASAP
The Microsoft Azure Network is fast and have enough bandwidth, just get on that network as soon as possible. Due to this a centralized internet egress is not a good idea for Teams, your connection is not faster than the Azure Network. Do not put obstacles in the real time media streams, like proxies or SSL inspection.
There are six ports that must be open in the firewall, TCP 80 and 443 and UDP 3478 to 3481, this is not optional. It is also possible to open for specific Office 365 URLs and IP ranges. Some firewalls even have a "open for Office 365" option which will be automatically updated as Microsoft is changing the IPs for Office 365.
The "Network Testing Companion" is a PowerShell GUI built for the "Network Assessment Tool".
The Call Quality Dashboard works with Measures, Dimensions and Filters in a SQL cube so that you could "query" the data in the follwoing way: "Give me the number of Poor Calls (measure) by building (dimension) for the past month (filter)"
The Call Quality Dashboard is a single page dashboard that provides an at a glance view monthly, and daily trends for call quality. CQD integrates tenant subnets and building data to provide location-based insights. Some 354 dimensions and 229 measures of call quality and reliability for audio, video and application sharing is currently available in CQD. The service is hosted in the Azure region where your tenant is homed, that is NOAM, EMEA or APAC. CQD is accessible by Skype for Business Tenant Admins or Report Reader roles, Global Admin is not required. As of Aug 2018, CQD includes Quality of Experience reports.
What is in the CQD Roadmap?
- Faster data availability and up to 12 months of historic data.
- Personally Identifiable Information (PII) will be in CQD so that user names, IP addresses, MAC addresses and BSSIDs will be found in the reports.
- Getting data to/from the cloud, Skype for business on-prem data can be uploaded via a connector, and Call Quality data can be downloaded using the coming PowerBI connector.
