LS Mediation Server error 25027 RRS feed

  • Question

  • Hi,

     

    I have an error when I try to make a call through a SIP trunk.

    The mediation server encountered an internal exception from the signaling layer. The current call can be deleted. The mediation server will continue to run.
    
    
    Exception : System.MissingMethodException: Méthode introuvable : 'Microsoft.Rtc.Internal.Collaboration.Media.CodecId Microsoft.Rtc.Internal.Collaboration.Media.H264VideoMediaFormatSet.get_CodecId()'.
       à Microsoft.Rtc.Collaboration.AudioVideo.MediaSessionAgent.ProcessGenerateAnswerWorkitem(GenerateAnswerWorkitemAsyncResult workitem)
       à Microsoft.Rtc.Collaboration.AudioVideo.WorkitemQueue.ProcessItems()
       à Microsoft.Rtc.Collaboration.AudioVideo.SerializationQueue`1.ResumeProcessing()
       à Microsoft.Rtc.Collaboration.AudioVideo.QueueWorkItemState.ExecuteWrappedMethod(WaitCallback method, Object state)
    Nom de la méthode : ResumeProcessingCallback
    
    Cause: Internal error.
    resolution:
    Examine the previous error messages in the event log to determine the potential cause and report it to the support services.

    Thanks for your help!
