OH YEAH!
Meh. There are a ton of services out there offering free conferences. Let me know when one gives away free toll-free conferences.
Google voice in your area code combined with a local landline phone gives you free long distance to anywhere in the U.S. except alaska and hawaii.
What's stopping someone from building a service that supports unlimited calls to another country (prepaid, probably), like putting an Asterisk pbx in each country?
Google-voice combined with a Fave5 or frans&fam plan from veri-tell beats the system. FREE FREE FREE CALLS TO ANYONE!!!
That's what I do, actually. I was fortunate to get an alltel u prepaid phone before verizon closed signups. I can call all I want for 0.75$ per day!
Curiously I recently found an 800 conference bridge by dialing random numbers, but it's pin protected. So far I've guessed 4 digits all the way to 0050. Available by pm if anyone wants to divide the guessing up.
