Awesome! I'm learning me technology!

Okay. So I've noticed that I can still call out using my tablet even if my home phone is currently busy. So I guess I'm not quite sure how Google Voice is actually using that phone line.

If I start calling stuff like my Psychic Hotline Friends, 411 Information and 1-976-Dial-a-Sweat tawdry smut action phone numbers, is my house number going to be charged for these ummm... quality services?

Is anyone using a forwarding number besides their house phone and is there any benefit for doing so?

Thanks ahead!
