I’ve been intrigued by this for a while, and after doing the sums we are seriously considering dumping our traditional phone line and getting a vonage Voice over IP (Voip) phone service. for ?9.99 a month you get unlimited local and national calls, and dead cheep international calls (and cheep mobile calls). no long term commitment and loads of cool stuff free. so far i have only found one hitch.
At this time Vonage does not offer the option to transfer your existing phone number. Please check back with us as we may offer this feature in the future.
Oh well, we might still do it anyway, and just have a phone sitting in the corner that we tell people not to ring.
