GoIAX, the Asterisk community's free IAX provider, is offering free US dids now. I loaded about 175 dids in and put up a very beta sign in page. Unfortunately I had to restrict the free us/canada outbound calling back down to toll-free only. There was a lot of war dialing and prank calling going on. I'm working on some stuff to hopefully curb that kind of stuff down so I can unrestrict outdial again, but this is the problem with free.. there is always someone that will abuse it. If anybody has any ideas on how to keep the abuse down let me know. The best ideas I have now is to only allow a certain amount of calling per month, add velocity checking, and somehow put some accountability into the sign up process to keep the prank callers and multiple account abusers away. yours, Matthew Simpson GoIAX -- www.goiax.com TxLink -- www.txlink.net
That really is a shame, goiax.com has been the best free termination service I have seen. The call quality was excellent, better then some paid services I have used. One idea, I'm not sure if you already did it, only allow one concurrent call per account? And now DIDs, thanks from all of us for the great service.

You could also change the signup so that we have to provide a pots number as a contact point. Otherwise I'd be happy to be limited to (say) 100 different numbers I can call, that would limit the wardialers at least. Keep up the good work.

I have been using goiax for my outgoing and has been excellent in quality of voice and also the service. To put the abusers out, I propose that each account holder should pre-register the phone numbers they typically call. For a legitimate user, pre-registration is certainly acceptable (especially for a free service), and if we give option of uploading an outlook address book or so, that would even simplify the process. Pre-registration of outgoing calls will make abusers' job lot harder and it is lot easier for hunting down the abusers as well. If you want, you can set a maximum pre-registration limit as well. To avoid multiple account holders, i would take an approach of comparing IP addresses at the time of registration itself. Suppose, if I want to create 100 accounts for 100 email accounts, i will have to go to goiax.com and register each and everyone of them; then collect the IP address of the request and check against the existing accounts; you can set a maximum cap on the number of accounts that could be registered from an IP (to allow roommates). If you set a max-cap to be 4, we can have all 4 roommates have their own accounts with each having pre-registered phone numbers. You can use similar tactic to restrict the service users as well at the time of allowing the outgoing call. . just my thoughts to get the great service going. regards, Rajesh ----- Original Message ----- From: "Matthew Simpson" <matthew@txlink.net> To: <asterisk-users@lists.digium.com> Sent: Tuesday, October 18, 2005 2:05 AM Subject: [Asterisk-Users] free dids on goiax.com> GoIAX, the Asterisk community's free IAX provider, is offering free US > dids now.

Why not just ask for a small one time payment $1 or something from a credit card, or paypal, or something along those lines so you would have someway to trace back to an abuser.

I completely agree. No reason to provide unlimited free service, put some reasonable restrictions like no more 10 different numbers could be called a day or no more than 20 calls a day.

Granted, there are many types of and theories for identifying spam and other unwanted messages, but what about adapting something that could be applied to this telephony service? It could learn what sort of "threat" an account poses by examining number of outbound calls in a time frame, duration of said calls, consistency in calling specific numbers, etc. Something that would identify suspicious behaviours/actions... -a

Frequency of calls and duration of calls. The more calls per hour (or whatever) the higher the probability someone is doing something undesirable. The shorter duration those calls are the higher the probability. Wrong numbers are typically fairly infrequent, when someone dials one they dial the correct number and go on from there, so a couple short duration calls isnt a cause for concern. However a bunch of short duration calls either continous or as an average indicates something that is not desired. Ultimately it boils down to some fairly simple math to start rejecting calls. -- Trixter http://www.0xdecafbad.com Bret McDanel UK +44 870 340 4605 Germany +49 801 777 555 3402 US +1 360 207 0479 or +1 516 687 5200 FreeWorldDialup: 635378 -------------- next part -------------- A non-text attachment was scrubbed...
