Setting Fusion up is pretty simple – the router hooks up just like any other wireless router and pairing it with the phone is just a simple button press. And that’s pretty much it, you’ve then got a mobile phone that will automatically switch to VoIP when you’re in range of the router.
How well does Fusion work? To be honest, it works very well indeed and the switch from broadband to cell coverage is totally seamless. I initiated a call from inside the house via the BT Broadband connection and the call quality was superb – it was almost impossible to ascertain a difference between a call made over Fusion and one made directly from the landline. While talking to Benny on the phone I proceeded to walk out of the front door, down the stairs, out onto the street and then about a mile up the road. Neither Benny or myself could tell when the phone switched from its broadband connection to the BT Mobile cell coverage, it really was imperceptible. I tried the same experiment the other way around, making a BT Mobile call and walking back home – according to the phone it had switched to BT Broadband as soon as it was in range, but obviously it’s harder to tell this way around.
So, Fusion does exactly what it’s supposed to and does it very well. The transition between networks is seamless, the VoIP calls over BT Broadband offer some of the best call quality I’ve encountered and once setup, everything just works. If there’s one issue it’s that the cost of the calls isn’t quite as low as I would have hoped.
The BT Fusion 200 Evening and Weekend plan obviously means that you get free calls in the evenings and weekends to any UK landline via BT Broadband. However, what shocked me is that calling a different mobile network via BT Broadband will set you back 30p per minute – that’s exactly the same cost as making the call on the BT Mobile cell network. Now you can use the bundled 200 minutes via BT Broadband as well as when you’re on the BT Mobile network, although this wasn’t made very clear until I queried it with BT. It’s also worth remembering that you’re still going to have to pay for your BT Broadband after the first three months, which is going to set you back a minimum of £17.99, or £29.99 with a far more realistic 40GB a month download limit.
