VoIP is any time you take sound and packetize it using standard (H.323, SIP, etc) or non-standard (Cisco's Skinny) protocols, which, in turn, allows one's voice to travel over IP. When you use VoIP to inmitate and/or expand upon traditional POTS telephony (ip-to-pstn, call forwarding, call-waiting, the stuff that Howard says above), it is more-encompassing to use to use the term IP Telephony.
Internet Telephony -- well, the word Internet implies that data is traversing different ISP backbones (autonomous systems) between the two or more VoIP callers. I would say Internet Telephony is one way to do IP Telephony but that IP Telephony doesn't need to use the Internet such as when it is used on a LAN only or when the WAN does not traverse the Internet.
