Interesting that Vodaphone's own information booklet about Home Phone features a prominent holding shot of a lady using an old rotary dial phone, and then the first bullet point says:
Before you start using Vodafone Home Phone, please check you have:
• A touch-tone phone. If it’s not, you’ll need to get one.
Idiots!
Anyway, some info here might be of use?
