answer:They got customers and kept them. Actually it appears that Net2phone is still in business, so I looked further. Net2phone started in 1996, Merger with IDT feb 06, alliance with Telefónica May 06. Is a public company based in the USA. Skype founded in 2003 based in Luxembourg. They have relationships with a large network of hardware and software providers. And are owned by EBAY. EBAY is probably the biggest factor in both their stability and their continued success. I used Sunrocket, quality service and great price, but they didn’t manage well and debt forced them out of business. But unlike Net2phone they actually went out of business.
