VoIP is moving fast! Thousand of providers are one the market now. Recently I noted an interesting piece of software coming from Lycos, called “Lycos Phone”. Is still in beta but comes by default with lots of extra and nice to have features for free.
It is actually ad supported software which tries to put under the same interface a phone, an IM, a music player and IPTV. If you can live with flashing banners, you may download the software for free from http://lycos.globe7.com/ and give it a try.
