Skype, the most experienced software voice over IP, can update their Windows version. The publisher released the v4.2, which offers some improvements, beyond simple bug fixes.

This new version incorporates an indicator of call quality and a payment per minute facility on a Wi-Fi via Skype Credit. Skype 4.2 is also “HD Ready” by its designers, ready to work with HD cams “When they are there in the coming months.” The function of call forwarding is also back, says the editor.
