Some users may experience a reduction in call quality when a call is placed from an older version of the Skype software to the newer versions. Problems with call quality are inevitable given that the older versions of Skype are being used.

Each new release of Skype improves in audio and video quality. That is why we are asking our users to get the best possible call quality by upgrading to the newer versions of the software. The best call quality is experienced when both parties are using one of these versions:

Skype for Windows 3.2 or above: http://www.skype.com/intl/en/download/skype/windows/

Skype 2.6 for Mac: http://www.skype.com/intl/en/download/skype/macosx/

Skype for Linux 1.4: http://www.skype.com/intl/en/download/skype/linux/

These audio quality issues may arise only when you’re having a voice conversation partner with another person on Skype. It does not affect SkypeOut calls, i.e. calls made to landlines or mobiles, or any other features that Skype has.
