Many of you know Slashdot-a creative commons where all manner of open-source code jocks and other geeks congregate.
Many of the threads are not about coding, but come from members seeking advice. In fact, on 12/31 a Slashdot member named Futurepower posted a thread entitled "How Do You Make International Calls?"
In the thread, Futurepower asks: "How do Slashdot readers make international calls? I know about OneSuite, Vonage, Skype, and iConnectHere. I know that BigZoo is quitting business. What other telephone, VOIP, or other kinds of services are available? Is there any open source VOIP software that can connect directly through port 80, bypassing firewalls?"
Slashdot readers had much to say, and are adding comments still. Here's the link to the thread.
