Not only Demon, but just about every dialup access provider over here
has local call access. This is a result of the way the telco regulatory
framework works, which means that an alternative carrier (say Energis,
who pioneered the scheme) get enough of an ingress charge from BT for
it to be worth their while to carry the calls on their network. The
ISP provides Energis with so many call terminations that it's well
worth Energis (or whoever) providing fixed cost per line (no per call
charge) access. This works over here as local calls aren't free.
