I'm excited to hear Microsoft Corp. is expected to make Windows Live Messenger instant-messaging service available to beta testers this week. Testers report that invitations were sent out from Microsoft for the selected beta testers. It has been said Microsoft will be including additional VoIP capabilities in the first Windows Live Messenger release. Sources report Windows Live Messenger users will have the capability to place calls both domestic and internationally from PC-to-Telephone with incredibly low rates. Microsoft will deliver this in conjunction with MCI Inc. sources said, "MCI will then sell users blocks of VoIP time".
