I'm using JustVoip in my PC. Now I switched to Mac. How can i install JustVoip client for mac os x? This link (http://www.justvoip.com/en/websignup.php) is for non windows users. But I'm already an existiung user why should I signup again? Eventhough If I signup there, it is asking me to verify... the verify tool is a .exe file and Leopard doesn't understand it I'm verymuch thankful if u guys can help me out in this.
