Bigzoo had been serving us with good quality, cheap long distance service for the past few years. They have discontinued the service on January 31, 2005 giving economic reasons.
If you are one of those who use Bigzoo and are looking for a replacement/alternative, you can try OneSuite. The site looks pretty similar to Bigzoo, they have the same pinskip options. I guess both of them use the same backend software.
If you register using the following link, we both get 20 free mins.
And thanks in advance if you do. :)
