I work for Tossable Digits. We plan on offering UK landline numbers soon, forwarding to any number in the world (rates per minute depend on forwarding number). More than likely, if you PM me, I may be able to hook you up with a UK landline number before we deploy it fully.
Also, TossableDigits.com isn't just for mobiles. You can get a landline anywhere in the US/Canada and forward to any US/Canada number currently. Soon, we'll offer world-wide forwarding and Real Numbers virtually anywhere in the world.
