Voipfone for Your BT Landline

Voipfone for Your BT Landline

The Voipfone landline service allows you to use your existing telephone equipment and BT telephone line and number with our advanced features - no VoIP or even broadband needed! And it's cheaper!

It can be used by anybody with a BT line and is especially useful if:

How Much Does It Cost?

Conversion to Voipfone's service is free of charge. You will only be charged for your outbound calls at our standard rates. Compare that with BT charges. A standard BT Business call to an ordinary 01 or 02 number during the day now costs 20p per minute and has a connection fee of 9p. That means a 1 minute call to a UK landline costs 29p. Voipfone charge 1p and have no connection fee.

To celebrate BT's price increases, we're dropping our own set-up charge so that the service is now absolutely free. Calls are charged at our normal rates. Click here for Voipfone prices.

How Does It Work?

Just like changing who bills you for your gas and electricity you can also do the same with telephone calls - you simply transfer your telephone billing from BT to us.

But unlike gas and electricity - where you still get the same old product as you did before you transferred - with Voipfone's landline service you get not just lower telephone bills but also access to features and services such as call transfer, call hold, music on hold and call recording.

Not only that, but you keep your existing telephone number and use your phone in exactly the same way as usual - no codes to enter or adapters to buy. You can still make calls using BT anytime you want to and switch back to BT permanently anytime too; so there is no risk at all.

CPS (Carrier Pre-Select)

CPS (Carrier Pre-Select)

Carrier Pre-Selection (CPS) is a service that allows our users to make calls via Voipfone, but over their traditional BT telephone line.

It enables our users to make these calls without having to dial a prefix, or install any special equipment at their premises.

Ordering CPS or carrier pre-select as it is otherwise known is simple, and can be enabled from our online control panel.

Once CPS is enabled on a user's line all calls are billed and deducted from the user's balance in real time.

Please note: this service is not available with BT's Digital Voice phone service.

Frequently Asked Questions

I've already changed my provider - can I still use your service?

You must be paying a BT line rental to use our service. If you've switched your LINE (ie not just your calls) to, say, the Post Office or TalkTalk you won't be able to use us. If you are still paying a BT line rental you will be able to.

Can I call other Voipfone customers for free?

Unfortunately not. As we have to pay BT to carry your calls over their wires until it gets to the Voipfone network we have to charge you at ordinary rates - 1p per minute.

How do I make a call using BT?

Prefix your number with 1280.

Do I still have to pay BT for my line rental?

I'm afraid so. BT still provide your telephone line and number; Voipfone provide your outbound calls.

What happens when people call me (inbound calls)?

Inbound calls work exactly the same as they always did - our services are only active on outbound calls.

Can I use things like call transfer, call recording etc for incoming calls?

No - our services can only work on the calls that we control, that is, calls YOU make. Incoming calls are still controlled by BT.

How many simultaneous calls can I have?

We can squeeze two calls onto your line but one of then must be on hold. The on-hold caller will hear music and you can switch between them as you like.

Will my broadband still work?

Yes, it will work as normal.

Will my fax machine still work?

Yes, it will work as normal.
