After much hassle I finally signed up with Lingo, a VoIP provider that just started offering unlimited calling to Western Europe for $20 a month.
Other than multiple firewall configuration problems as usual (2Wire’s router is buggy as hell when it comes to DMZ configuration) I am very impressed with the solution.
Three calls to Spain with perfect quality on my end (and only one short instance of “echo” reported on the other end) gave me the best
We’ll see how well it fares when I plug the ATA (Analogue Telephone Adapter, in their “lingo” :-)) to the DSL connection in Spain. The real use I intend to give it this summer!
