Talkster is a great concept, and when functioning, is very handy while I'm in Mexico and my family in the US. However, I've had more problems with it suddenly disconnecting in the middle of calls, then quality phone calls. I hope they can work out these kinks.

Talkster's Free World Dialing gives an easy way to make long distance calls, international calls and conference calls with up to 5 friends, all FOR FREE. There is never any charge for making your long distance or international calls from many international destinations. Just tell who you want to call and at what number you want to ring them, and Talkster will provide you with a local number to dial to initiate the call.
