Starting a small business, central London location. We make minimal calls using a fixed landline as we use mobiles most of the time. We have no fixed/BT landline but we have wi-fi broadband. We wish to have a ‘normal’ landline number to give out to clients. I have heard the names Skype/Vyke & sipgate being used.

How can i get a 020 7 number?

Can you recommend any particular providers?

What is the cheapest option?
