VoIP closed systems (as opposed to Open Standards (such as SIP, H.323 or MGCP)
AOL, Yahoo, and Apple all offer "voice chat" capability via their instant messaging networks. These systems are closed and for the most part unable to interoperate with other, standards-based products and may use undocumented protocols. However, even where the protocols are known or have been reverse-engineered, the audio codecs are proprietary. It is known that AOL's voice chat uses codecs from Qualcomm, Yahoo's uses TrueSpeech from DSP Group, and Apple's uses PureVoice QCELP.
The popular Skype service is similarly closed. It is known to use three audio codecs: iLBC (Internet Low-Bitrate Codec) and iSAC (Internet Speech and Audio Coder) from GlobalIPSound, and a third as-yet unidentified codec. The Skype protocols have not been reverse-engineered.
