Metrics for Media quality reported to the Skype for Business Server 2015 (RC) Monitoring Server database (Quality of Experience database) for each audio call. At the Skype for Business Server 2015 (RC) Monitoring Server each call is categorized as having Acceptable quality or Poor quality based on a set of network and audio metrics. The audio quality of calls in different network locations (that is, subnets, sites, regions) and media infrastructure (that is, conferencing servers, Mediation Servers, gateways) is monitored by the Skype for Business Server 2015 (RC) Monitoring Server every few minutes.
Media Quality alerts are available for following categories:
A/V Conferencing Server
Calls between A/V Conferencing Server and client endpoint.
Gateway (Mediation Server Bypass)
Calls between gateway and client endpoint that bypasses the Mediation Server.
Gateway and Mediation Server Leg
Calls between gateway and Mediation Server.
Mediation Server and Client Endpoint Leg
Calls between Mediation Server and client endpoint.
Calls between Regions

Calls between Sites
