      They usually aren't exactly free. Typically if you read the fine print, there's some deal where the monthly service will include 400 or 500 local calls "free", and then you pay through the nose for additional local calls. I would bet these clauses are there to specifically prevent a re-seller situation like this. An open public line could probably hit the 500 call mark rather quickly.

    P2P networks like this are built on foundations of trust, a foundation which does not exist.

    Beyond the toll dialing (which could be prevented by proper configuration of the PBX software), the bigger concerns are leechers (long distance is a huge cost for advertisers), scum (nice, anonymous, robo-dialers with prerecorded spam messages), and tapping (it might be worth it to set up a few PBXs just to listen in on others conversation!).

    • and thought there are various levels of non-anonymity of Internet access, this adds another layer of insulation between the harrasser and victim.

    • Bellster actually defends from leeching. From Bellster's website:

      The Bellster Network keeps a tally of calls that you make and that you give to others. It's like getting a calling card that starts with a few credits. One credit is used for each call and you get credits for each call that you give. As long as your balance remains positive, you can place calls.

    The idea is great for the US where you have flat rate local calls, however I see it will very diffictult to find somebody volunteering their phone lines in South America or any country where greedy phone companies like Spain's Telefonica run the show. In there you pay per minute for you local calls and I can see somebody's phone bill growing exponentially.
    • For each local call you let someone place through your phone, you get a long-distance / international call in return. So it still sounds like a pretty good deal.
    • Well for every incoming call you handle you get 10 outgoing credits. Outgoing credits you can use for long distance.

      So you set the incoming usage limit to like 2 calls per month. For the cost of a few local calls you get essentially unlimited free long distance.

      Heck, if you don't make many long distance calls you could accept a single incoming call and shut it down. You can then use those 10 credits for lite long distance usage over the next SEVERAL months.

    This is what FWD used to be back in 2000 or 2001. I don't think it ever made it past the beta stage. It wasn't P2P persay, but anyone using the network shared their phone line to make calls in their local calling area.

    When you signed up, you put in the area codes/prefixes that were local, and when someone made a call, custom software on the Cisco ATA-182 device checked with the server to see if someone resided in that area and had an open line. If so, the call was routed over the net, the remote ATA-dialed the number, and you were patched through. If no one was in that area, your local ATA device dialed it out on your own phone line.

    The project was damn cool. However, the ATA-182 had some serious hardware bugs, and probably was the greatest contributor to the demise of the project. The original plan was to get FWD branded ATA's into stores like Best Buy so anyone could pick one up and contribute. As far as making money, I think they were betting on profit from hardware sales, but I'm not sure.

    FWD went away for awhile, and then re-emerged in its current incarnation. Hopefully this will address some of the security problems that were present in the beta, like the ability to dial a remote user's device by IP and be patched through to a dial tone. By doing this, you avoid the access policies and you could dial 911 or make LD calls on someone else's phone. Not good... at least for the victim.

  • The funny thing is that once you have an asterisk box working you can hook up to some very cheap VOIP providers (much cheaper than the phone company or even the "retail" VOIP providers).

Bellster is a disruptive technology, and Jeff Pulver is all about that.

You can choose any of the following bootable CDs to turn any old PC into an Asterisk box with just a Control-Alt-Delete. Not a PC fan? Asterisk now runs on Mac OSX, too. Now the only real barrier is the hardware, an FXO interface to connect to your POTS line. Just such an interface is reasonably priced at Digium.com, the makers of Asterisk.

    Don't want to spend all that just to join the free love revolution that Bellster hopes to be? Well, Asterisk has tons of other uses, like being a PBX for your home or office, too. Set up mailboxes for each member of the office or household. Email an incoming voice message automatically. Zap the telemarketers that don't pay attention to the do-not-call list. The list goes on as far as your imagination: Asterisk makes computer telephony accessible to everyone with a computer. Even if Bellster isn't the future of telephony, Asterisk is.

An optimist believes we live in the best world possible; a pessimist fears this is true.
