For what its worth, I've used ViaTalk for more than 5 years at our NY home and have been very happy with it. I particularly like the extensive capabilities they have to block unwanted calls. You do need a good solid Internet connection with enough upload bandwidth, but most every high-speed Internet providers offer that nowadays. I'd say 1 megabit per second upload would be a practical minimum for most households, but of course more is better (up to a point).
