Cause: The Audio/Video Conferencing Server being unable to reach the Audio-Video Edge Server may be due to network connectivity issues, or the Audio-Video Edge Server pool being unavailable. This will impact Audio/Video Conferencing Server for users joining from outside of the enterprise network. This will also prevent the enforcement of Call Admission Control, if it is deployed.
Resolution:
Please ensure connectivity and availability of the Audio-Video Edge Server for the Audio/Video Conferencing Server to verify this issue is corrected. Note: In Case the Audio-Video Edge Server is not deployed, and only a Call Admission Control server is deployed, this alert means the Audio/Video Conferencing Server is unable to reach the Call Admission Control Server.
