What is Half NAT entries for the VOIP means

SHOW IP NAT NOTIFICATIONS (if any)

INFO: Half NAT entries found for the host 10.0.19.18.

When some well-known ports such as H.225 Call Signaling traffic are involved, NAT

will look at the payload and translate embedded IP addresses. Half NAT entries

are normal when using VoIP traffic. NAT entries will be complete while running

another service such as FTP.

Could some one tell me what is mean by :
