Has anyone tried the free peer2peer VoIP software – Skype. (I am nothing to do with the product, but only a user by the way). At the moment it provides basic call set up and directory functionality, but the call quality is really good. I had a call between UK and AUS (both broadband connected) and the quality was as good if not better that a PSTN call. I understand they are planning to develop for WiFi, and also BT is planning to implement something similar in the summer, with added features (vmail, PSTN breakout) I would be interested to know if anyone has tried using this in a business environment.
