Is Sky Talk Anytime Extra redundant if all calls are VOIP?

[TapeHead]

Not sure why this has just occurred to me but if all calls are via VOIP then why do I still need to subscribe to Sky Talk Anytime Extra?

Internet calls are charged in exactly the same way as standard calls. They're not free.

Strangely, telcos are reluctant to give up what's been their primary income source for a century.

Note that Sky billing which uses the word 'Free' against Sky Talk Internet Calls is intended to refer to availability of voice service, not outbound calls themselves.
