How is the cheapest way to set up call divert?

basically im trying to expand into a different town and have found a good local number to that town...been thinking about getting a mailing address in the town so it looks like i have a business presence there...

If i get a "call divert" to divert the new number to my existing number set up with B.T it will cost me a fortune every time someone phones me...Is there another way?? I dont want to pay for the customer phoning me asking me all sorts at my expense.

One possiblity (no idea if this is actually possible).

Phone call to Skype Enabled Phone -> PC -> Broadband ----- Broadband -> PC -> Skype Phone..

I hope you get what I mean here I do believe there are systems (no idea how inexpensive thought)

that allow you to set up a branch with only a BB link and give them access to phones via that link.

You could do it that way using VOIP, but its not 100% reliable also you would need somewhere to sit a PC

You could get an 0845 or 0870 number (local rate) and piggy back it onto your existing number then people dont know where you have or havnt got an office......

Hope this is ov some help
