Failure analysis apparatus, failure analysis system, failure analysis method, and failure analysis program

摘要

To provide a fault analysis apparatus for easily detecting the occurrence of a network fault with a possibility of hindering a voice call and recovering from a fault quickly.A DTMF signal adding unit that adds a DTMF signal to the RTP packet to generate a failure detection signal, a transmission unit that transmits the failure detection signal to another failure analysis device, an RTP packet generation unit that generates an RTP packet, A receiving unit that receives the failure detection signal returned from the other failure analysis device; a detection unit that detects a problem module in the failure analysis device based on the DTMF signal included in the failure detection signal received by the reception unit And reboot means for rebooting the problem module detected by the problem detection means.(FIG.
