This is an excellent site but you'll find a lot more assistance by going to the (almost) 'sister' site the MoneySavingExpert.com site and asking the same question there.

Sorry to go on about Sipgate again.

But as you have a Telewest broadband connection, then you are in the ideal situation to get rid of your landline altogether.

You can get for free and no monthly cost a number from http://www.sipgate.co.uk , you can choose any area you like it doesn't have to be your own locality, you then make and receive calls using VoIP.

I would add this to 1899's VoIP service.

You can use software or hardware phone, or use an adaptor to enable a standard phone to connect.

There are many phones and adaptors to choose from, not just the few on Sipgates site.

With Sipgate you get a real telephone number, not yet available with Skype (Skype-In when launched).

You must be aware at the moment 999 service isn't currently available via Sipgate, so having a mobile available would be a good idea.
