What are we supposed to call a number that is not free and we have to pay for it? Paid call? Toll call? The call is made in the hometown.
A charged call.
There is variation in different semantic areas:
a toll road, toll bridge
a pay toilet
(I should add that 'toll call' is used in two senses: 'long-distance and charged' and merely 'charged'. I've seen 'local toll call' used to disambiguate. I should think that the US prefers 'toll' and the UK 'charged' – but we'd agree that 'free' sounds better.)
