Skype

Skype is the software application I'm using to make calls from my laptop computer to family and friends back in the U.S. while I'm in India.  (I also have the iPhone version on my iPod Touch, and tested it successfully.  Just not sure where that iPod is at the moment.)

I can make voice and video calls from computer to computer for free.  I just had to download Skype, setup an account, and buy and install a webcam so I could add video.  My webcam also serves as my microphone.  You can also use a computer headset with mic that you plug into both the 3.5mm mic and headphone ports on your computer, but some also connect via USB.  Skype.com can probably explain it better. 

For iPod Touch and iPhone, only voice calls can be made.  For the iPod Touch, you'll need the iPhone headphones with mic because the Touch lacks a built in mic.

Skype also offer options if both parties don't have a computer.  They offer cheap rates on calls from computer to landline or mobile phone.  I purchased a monthly plan for $2.95 that gives me unlimited calls from Skype to phones in the U.S.

If you buy a webcam, I recommend installing the drivers from the CD-Rom provided in the package.  Otherwise your computer may not recognize the new hardware correctly, and that could cause problems when you go to make calls.  Skype has a test call feature that is very helpful, and better than frustrating an embarrassing yourself if you connect with someone but your mic is not working properly.  I did that once.  Video worked, but audio did not.  Very frustrating.
