Companies all over the world use Skype for business. Voice over internet Protocol (VOIP) brings considerable savings in communication costs.
Aside from communicating through voice and chat, employees have found additional features such as a Skype video call recorder very useful especially in documenting important conversations. All you need is a stable internet connection with sufficient bandwidth with at least 400kbps (for video calls), audio devices and a computer that is fast enough to run Skype.
The versions compatible with Skype are Windows XP Service Pack 3, Windows Vista, Windows 7 (32-bit and 64-bit versions supported) and Windows 8 (Enterprise N or KN). The processor needs to be at least 1 GHz with at least 256 MB of RAM. Downloading DirectX v9.0 or above will also be required.
Mac users with OS X v10.6 (Snow Leopard), 10.7 (Lion) or 10.8 (Mountain Lion) can download the latest version of Skype. You should also have at least 1GHz Intel processor (Core 2 Duo) and at least 1 GB of RAM. The latest version of Quicktime is also required. (Note: Mac OS X v10.5 Leopard does not support Skype for Mac 6.4 and higher.)
