I've used CDR for that and don't automatically accept payments. When we receive a payment we compare: 1. IP Address of user (whois normally gives approximate location) 2. Paypal account holder email (should match sign up email) 3. Countries for emails and ip address should match. 4. Initial payment should be $1-$2 (i.e. noone is going to sign up for a service and in order to test it put down $500 via paypal) If any of the above look suspect I ask the paypal account holder to email me and start looking at email headers to see how sus it looks. If it's a large amount then they have to have already been doing business with us successfully with small amounts - most scammers can't be bothered doing this. -- Cheers, Matt Riddell Director _______________________________________________ http://www.venturevoip.com/news.php (Daily Asterisk News) http://www.venturevoip.com/st.php (SmoothTorque Predictive Dialer) http://www.venturevoip.com/c3.php (ConduIT3 PABX Systems) _______________________________________________ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- AstriCon 2009 - October 13 - 15 Phoenix, Arizona Register Now: http://www.astricon.net asterisk-users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
