MSN gets into Internet audio
Also yesterday, Microsoft announced that it bought Teleo, a provider of voice over Internet protocol [VoIP] technology. Currently MSN also uses similar VoIP technology in MSN Messenger, but has not yet incorporated into the public switched telephone network [PSTN]. I have been using VoIP PSTN service through Packet8.net and so far have been quite impressed [in the pocket certainly, and call quality as well]. I should also note that Microsoft has used other VoIP technology before deploying it's own, but Microsoft .NET Voice Services as it was known was discontinued in software updates in 2003.
The technology certainly looked cool, I hope MSN uses it well.
