• PC running Windows® 2000, XP, Vista or 7, both 32- and 64-bit operating systems. (Windows 2000 users require DirectX 9.0 for video calls).
• Internet connection – broadband is best (GPRS is not supported for voice calls).
• Speakers and microphone – built-in or separate.
• For voice and video calls we recommend a computer with at least a 1GHz processor, 256 MB RAM and of course a webcam.
• Group video calls can be between three or more people (up to a maximum of 10),
and at least one person on the call needs a group video calling subscription.
For the best quality, we currently recommend video calls with up to five people.
• For group video calling everyone on the call needs the latest version of Skype for Windows plus a webcam.
You'll also need a high-speed broadband connection (we recommend sustained 512 kbit/s downlink or more)
and a computer with a 1 GHz processor (minimum) or Core 2 Duo 1.8 GHz (recommended).
• We also recommend a minimum of 1 GB memory and 2GB memory for group video calls with up to five participants.
