Anyone using this service for free software VOIP calls? There is a limit on how many calls you can make per trial username, but you can easily open new accounts. I abused it for 2 days, and they finally banned my ip address from the registration server. Conference calling, as well as international calls to many locations is supported. I connected a call center worker at QVC to a local Wal-Mart. and they argued for over one minute about who called who. The woman working at Wal-Mart constantly accused the QVC guy of prank calling the store. Wal-Mart received many interesting (conference)calls that night, including a woman from Hong Kong and a guy from the Netherlands.
