This failure can be caused by network performance issues affecting the endpoints or an endpoint being unable to use the A/V Edge Server. This is a federated call where one endpoint is internal and the other is remote. Correlation of such failures with individual networks, endpoints or A/V Edge Server can indicate potential deployment issues.Ī federated call failed to establish due to a media connectivity failure where one endpoint is internal and the other is remoteĪ federated call failed to connect because a media path could not be established between the two parties.

Correlation of such failures with individual networks, endpoints or A/V Edge Server can indicate potential deployment issues.Ĭall failed to establish due to a media connectivity failure when both endpoints are internal The most common cause for this is that a legacy client in the conversation needs to be patched (KB 2028888). The unknown endpoint is most likely a legacy client, legacy component or third party application. The call failed to establish due to a media connectivity failure.
