List of "junk" caller phone numbers for UK?

I have to say - this TrueCall gadget is awesome! I know its not super cheap, but the amount of time I waste answering junk calls while working, it'll pay for itself in about 20 cold calls

We put it in yesterday lunch time, and 30 minutes later it blocked someone. Looking up in the control panel, it gives the phone numbers of all the incoming / outgoing calls (and what happened to them). I looked up the number that was blocked, and sure enough it was some Indian call centre. So job well done so far! I still need to add my friends, family and common callers to the whitelist, but it shouldn't take too long. I actually don't think I need to find a list of spammers to block (the original intention of this post), as I recon it'll do a good enough job of blocking them at source.
