Alert for event Id: 32018 ('AVMCU_E_MRAS_REQUEST_FAILED')

Microsoft.LS.2010.Monitoring.Rule.InfoEvent.AVConf_AVMCU_E_MRAS_REQUEST_FAILED (Rule)

Knowledge Base article:

Summary

The Audio/Video Conferencing Server cannot reach the Audio-Video Edge Server.

Causes

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.

Resolutions

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.
