Just to mention to all those VoIP users out there in CF land that you can now call to any UK land line (01 or 02 codes) for FREE and NO CONNECTION fee with 1899's new service.

Calls to mobiles are charged at 2ppm
Also worth noting that calls to the USA, Germany and Canada are also free. The quality's not that great but it's acceptable seeing as your not paying for it.
Wonder if any of the other providers will go down this route?
