I use Skype to make phone calls to the UK and the US. Can't call UK mobiles or 0870 numbers. Wouldn't if I could.
If ever anything made this country of ours look cheap it's that grasping @$$%& phone system. Just back from Texas where I rarely have to pay for a single call. If I do, it's via the same Skype system I purchased in the UK. I didn't know it would work there, but it does.
For Pete's sake fight this embarrassingly cheap idea of charging these rates even for things like calling your bank. For hell's sake, even the numbers given to me by my personal bankers have now been cancelled. 'Say no' really needs input, and every normal landline number I obtain gets fed into their system.
Right, carry on, chaps.
