ABTolls lists long distance phone providers by price, taking surcharges and in-state rates into account.
In Wisconsin, AireSpring Global FiberNet offers the excellent in-state rate of 2.25¢ per minute. Their interstate rate is 2.85¢. We used their service and had no problems from February 2004 until May 2005, when we switched to VoIP (see below).
Another quality company is Pioneer Telephone, although their Wisconsin rates aren't quite as good as AireSpring's.
Voice over IP uses your internet connection to provide full-featured phone service at much lower cost and somewhat lower reliability than conventional telephone.
