Hi
@ANAND_SUNKAUse Call Analytics in the Teams Admin Centre to troubleshoot call quality problems with specific calls
https://docs.microsoft.com/en-us/microsoftteams/difference-between-call-analytics-and-call-quality-d...As described
Call Analytics shows detailed information about the devices, networks, and connectivity related to the calls and meetings for each user in a Microsoft Teams or Skype for Business tenant account. Why did this user have a poor call this afternoon? With Call Analytics, an Office 365 admin or trained helpdesk agent can investigate the device, network, connectivity, and other factors related to a call to troubleshoot call quality and connection problems in Microsoft Teams and Skype for Business.
Hope that helps to answer your question
Best, Chris
