I just setup my Gizmo5 account with a Linksys ATA I got off ebay (I am late to the party, did not know I could have had free calls for years). But I got it for 1 reason only not to use it to call out but to use it with Google Voice. I use my Google Voice # for my second job as a Tech Support Rep for a hosting company and I work out of the house on the weekends and the phones have been forwarded to my Google Voice # then to my cell phone. The problem with that is ATT sucks in my house, it sucks so bad the neighbors got rid of ATT when they moved in. It is weird since the landline service is ATT so you think they would try and get good signal for cell service in the same area. No because ATT cell service is so bad in my area I have Google Voice forwarding to my Gizmo5 account that is going through my Linksys ATA to my cordless analog phone. So good by crappy ATT cell service for incoming calls. Now for outgoing I can use this but it will cost $0.010 to landlines and mobile phones in US and Canada. We shall see how well it goes.
