Free phone calls and telephone number

I started to explore Google Voice.  Wow.  A nice free app.  It gives you your own free Tel Number that has voice mail, and it transcribes it to (words) and sends it to you. Also you can forward it to your other phones.  I am using it for my co-working space.  The only issue with the number is that it does not have the local exchange (the first 3 numbers of your phone number).  So if you are a local business it may appear that you are not local.  But since its free, I cant complain.

BUT if you want your business to appear to based somewhere, you can pick that area code.  For example, I can be a certain politician from Wassila Alaska and have a DC area code.  People calling me will think I'm from DC when in fact, I'm not (and never will be).  

Using the phone is like using SKYPE.  Just place your call.  As long as you have a speakers and an microphone- you're good. Most laptops have these built in.  Its pretty easy and US calls are free for now.  Overseas calls are pretty inexpensive.

One thing that I would like to explore is conference calling.  Google has it covered. Thanks Google.

This link will take you to the google page explaining how it works.

 This is what the screen looks like.  The vids explain it much better than I can.
