1. Yahoo has a hidden cost. It charges for connecting time in line with US TELCOS. No other service does that. That clearly is unfair trade practice. 2. SKYPE is good and cheap but a little skimpy during peak hours. 3. Deltathree is stable but more expensive. Currently, the vote is for SKYPE with a warning that their gateway is getting a little bit too crowded with the attendant loss of voice quality. But on the +ve side, they offer a lot of other features, unmatched as on 03 August 2006 by others. psr
