We already pay to receive calls
I think El Reg is inadvertently scaremongering in this article, by leading readers to suppose we'll be expected to pay to receive calls including spam, wrong numbers, etc. If that happens it'll be by choice or when we're scammed. At least, I assume so ...
I for one have paid a lot for incoming calls over the years, without the option. That's because, as a one-man business (from 1998 to earlier this year) I had to ensure my landline would divert to the mobile and I wouldn't miss vital business calls. So the landline was being charged full call-to-mobile charges, and that's a sector where they seem to operate a cartel (no bloody competition).
Just to complete the scam, there was an idiot Estate Agent who kept giving my (landline) numbers to his customers, so I'd get their calls at my expense. Being a public-facing business, they had about 100 incoming calls diverted to me for every business call I got.
 The callers always asked for "Ben". There were several other staff at the same agent, but never a call for anyone else. So I have to infer that it was Ben who couldn't give his own phone number, rather than lots and lots of customers getting it wrong.
