1. You are being asked to code this for RIPE NCC ...
For the record, I agree completely with Sascha Luck on this one. CAPTCHAs are an awful idea in this context. I hate them. Everybody hates them. They are only useful when one is trying to keep random anonymous idiots from spamming your blog... a blog which otherwise allows comments from random anonymous idiots. But we were discussing validation of phone numbers allegedly belonging *not* to anonymous people/entities, but rather to people/entities that are in fact *known* to RIPE (and which already have, or which can pretty easily create a RIPE login account). Bottom line: I don't see CAPTCHAs as being at all useful in a phone validation system. That having been said it might still be either necessary or advisable to put a CAPTCHA in front of the RIPE account creation process, e.g. if there isn't one there already, just to stop some mindless automaton from trying to create 100,000 new RIPE accounts on some given day.
