SIP, VoIP the standard way
Making SIP Make Cents provides a basic description of how Session Initiation Protocol and related protocols work. Most VoIP systems over the Internet now uses SIP, with the exception of Skype and a few others. Within enterprises there's still some use of H.323 and maybe even MEGACO. Actually Microsoft's NetMeeting uses H.323. SIP is inherently a much simpler protocol than H.323, but as always, as time passes it's grown into a beast of its own.
IP Multimedia Subsystem (IMS) is also based on SIP etc, which is a good choice, and SIP will be a key component in the All-IP concept of future mobile networks.
