Help: Conference calling for 10,000+ participants. Who would you use?

A reader called me this morning to ask for a recommendation on a UK company that they could use to run a conference call (like a Shareholder/Earnings call) for upwards of 10,000 participants. They’ve talked to the usual suspects who are all about to offer 100-1,000 concurrent users, but after that level, the list of suppliers appears to dry up to next to nothing.

Do you have any suggestions I can pass the reader?

He’s looking for a UK company — but if you’ve got any international suggestions that would supply a UK dial-in number, that would still work.

Email me or post below? I’m

Update: Scott Curzon from Bridge Talk got in touch to say that his company holds the Guinness World Record for the largest conference call ever (10,424 participants) and that they have dial-in numbers in 67 countries around the world. Probably a good company to talk to, if you’re in the market for these kind of services!

    The software to do a project like this is easily available assuming that only a small group of people were talking.
    However to have 10,000 people connected to a conference call by the telephone network you would need 334 ISDN lines, two racks of servers. There's not much demand so the setup and running costs involved means it ain't going to happen.
