(3) RTP monitoring
RTP monitoring is the feature that monitors whether an RTP is received during call, by using the SIP
with connected party. If RTP is not received a certain amount of time (about 10 seconds) from SIP
trunk to CPU blade, a fault notification is sent and the call is restored to normal state. By this feature,
you can avoid occupying channels if a disconnected message is not received because of a network
failure.
