Microsoft has chosen Telefonica to provide VoIP services to Windows Live Messenger customers in Argentina, Brazil, Chile, Colombia, Peru, the US and Venezuela.
The operator will use Microsoft's online channels to promote the new service and plans to use a package strategy with its Speedy ADSL lines.
Telefonica's Voype offering will enable Windows Live customers to make calls directly from their PCs to any fixed or mobile phone worldwide without leaving Windows Live.
During a second phase, Windows Live users will also be able to receive calls to their PC (PSTN-In). The service is already available in the US and will soon be in Argentina, Brazil, Chile, Colombia, Peru and Venezuela.
