I'm a newbie at Google Voice and VOIP and I've been trying to understand more about this stuff. I got a Google Voice account, a sipgate phone number, registered it on SIP Sorcery, and downloaded sipdroid onto my Droid phone. I made an outgoing phone call and it seemed to work fine. However, I have a few questions and would GREATLY appreciate some clarification. Basically, I would like to make and receive free phone calls to people outside of my cell phone provider and/or not in my Friends and Family network, and yet not use my anytime minutes to do so. It seems like there are many ways to accomplish this using Google Voice:
1. Using the sipgate + sipsorcery + sipdroid method with a wifi/3G connection
2. Using a "callback" app like Google Voice Callback
3. Using an automated dialer app like GV Dialer or GV Mobile
My questions: Are each of the above methods free from anytime minutes usage? If so, which are the easiest to use (as far as dialing, etc) and most reliable? Also, would they all work equally well if I am driving and therefore not remaining in one location? Can any of them be used for free texting as well? Thanks for your help!
