Microsoft has purchased internet-calling startup
Teleo, which may enable them to offer features in MSN Messenger similar
to what SkypeOut offers — the ability to make a phone call from your
computer to an ordinary telephone.
Google Talk doesn’t currently have this ability, but the “wisdom of the crowds” predicts that Google will have a significant impact on Skype’s business (in addition to a very detrimental impact on Vonage, the leading commercial VoiP player.)
