Configuring Skype for Business Agent for Monitoring Call Quality Information

The Skype for Business Agent monitors only the SIP call flow. The call quality information is reported by the user agent, Skype for Business Desktop Client.

To get the call quality information:

1. Enable monitoring on the Skype server.
   See https://docs.microsoft.com/en-us/skypeforbusiness/deploy/deploy-monitoring/deploy-monitoring.
2. Install and configure the Skype for Business SDN API on the Skype Front-End Server, as described in the Skype for Business SDN API 2.4.1 Installation Admin Guide.
   See https://docs.microsoft.com/en-us/skype-sdk/sdn/articles/installing-sdn-interface.
3. After the installation, add the Mediation Engine machine to Skype for Business Server as a subscriber for the SDN API by running the following command in the Skype for Business Server console:

   SDNManager.exe /p s EOM submituri=https://<IP_address>/sfb/

   where <IP_address> is the IP address or the hostname of your Mediation Engine.

   The finished Skype calls show the MOS values and media summary.
4. Configure the SDN Manager to send QualityUpdate messages to the Mediation Engine by running the following command:

   SDNManager.exe /p s EOM "quality=True"

5. Operations Monitor reads the SDN Interface messages from the URL https://<Mediation Engine Host>/sfb/.

   cd "C:\Program Files\Microsoft Skype for Business Server\Microsoft Skype for Business SDN Manager\" SDNManager.exe /parameter subscriber ocom "submituri=https://<MediationEngine Host>/sfb/"

6. After configuring the SDN Dialog Listener and SDN Manager, run the following command for SDN Manager to forward the messages to Operations Monitor:

   cd "C:\Program Files\Microsoft Skype for Business Server\Microsoft Skype for Business SDN Manager\" 
   SDNManager.exe /parameter subscriber ocom "submituri=https://<MediationEngineHost>/sfb/"

7. Verify the SDN Manager configuration:

   cd "C:\Program Files\Microsoft Skype for Business Server\Microsoft Skype for Business SDN Manager\"
   SDNManager.exe /download subscriber

   You should get an XML describing the configuration.

   Note:

   Make sure the value of the submituri parameter matches the address of the Enterprise Operations Monitor machine.
8. Check the SDN Manager and Dialog Listener log files at %LOCALAPPDATA%\Local\Temp\SDN after each Skype for Business call. Open the SDNManager.log file and search for the following:

   Starting to transmit the message?

   If the line does not exist, the SDN manager is configured incorrectly. Repeat the configuration process again.
