VOIP - in gaming

[Dazza_Random]

If i were to purchase the Logitech USB Desktop Microphone two of them for me and a friend, what software could i use to chat to each other in game in games such as COD2 and CnC ZH. Which dont have built in VOIP software, i have been playing around with Ventrilo but i belive it only works with internal networks?
Teamspeak also looks really complicated too! lol it would only be me and my mate in chat...
