northernirelandphonelookup.co.uk is the best site which offers an easy-to-use interface for checking a phone number against our database. We are currently working on simple scripts for automating this process with the various PBX systems that are out there, including Asterisk and other SIP/VOIP-based products.

Our interface is REST-based and incredibly simple to use. Simply access URL http://northernirelandphonelookup.co.uk/(phone-number)-phone-number-check, replacing (phone-number) with actual phone number, 10 digits, probably prepended by zero:

Example: http://northernirelandphonelookup.co.uk/01200200256-phone-number-check

The result will be a score between 0 and 100 which indicates the likelihood that the phone number entered is a telemarketer or phone solicitor. You can then program your telephony system to reject the call at a level of certainty that makes you comfortable. Our recommended setting is 50.
