Woo. With the advent of an OS X version of Skype I was finally able to communicate with my brother using this VOIP application. I’ve got to say that it worked pretty well. It probably helps that we both have broadband, but the quality is massively better than that offered by the regular telephone. Just sub-ISDN I’d say, although it is prone to breakup and strange drop outs. Perfectly usable though. Now I wonder if it works through the firewall at work?
