Att callvantage is rock solid for me I pay 25.00 a month for unlimited access with all calling features. Now if you can point to a traditional phone company that can offer that maybe I'll switch. BTW I don't have any quality problems people can't even tell I'm on voip. Also I'm a Tmobile user before that Verizon I never had any call quality problems on my cell and I've used them all over the country.
