Frequent Disconnection in MS Teams Calls

Question

Hello Team

People are complaining that they are getting frequent call disconnection during the meeting, upon check the CQD it showing as packet loss, RTT was high and some time jitter was high

The issue in intermediate, Some times the calls are good.

Upon checking with network team, they are saying no issue at their end. its really a challenging one for me , to determine, where is the packet loss is happening exactly. network team checked thoroughly from Access point to WAN link and no issue observed,

What could be the reason, where can i find the network issue for MS Teams meetings / call.

In CQD it clearly says it was issue with high packet loss. which tool can clearly says about the location of the packet loss and other network impairments

how can we find out, if there is any issue at MS Teams server end during the issue.

Answer 1

Here are some ideas/thoughts:

1: If possible check the bandwidth (input/output) report for days that problems had been reported. In some cases, a high volume of uploads can actually cause network issues. Most of the time, upload speeds are smaller than download speeds, therefore upload speeds are causing a bottleneck.

Use utilization graphs to see if peak times correlate to incidents.

2: If your equipment has QoS capabilities, implement QoS for Microsoft Teams:
