SAF_UNKNOWN_SUBSCRIPTION - Unified CM sent a subscribe or unsubscribe message to the SAF Forwarder but the message contained a Service ID that was not familiar to the SAF Forwarder. Without a recognized Service ID, Unified CM cannot subscribe to the SAF Forwarder. Recommended action is to contact the Cisco Technical Assistance Center (TAC).
