phoenix, if I may make an alternative suggestion, I personally find the service offered by 'Internet Calls' superior to those of 'Skype', I often phone Australia and other far flung places, the recipient of the calls does not have to be a subscriber to any other than the normal telephone service.
An hour long conversation to Ozz 'FREE' can't be a bad deal, I found 'Skype', to be a little more troublesome but would not condemn it, merely compare it.
An initial subscription of 10 Euros gives you (I think) 120 free days, thereafter the calls are ridiculously cheap and an automatic top-up revives the free period once again.
Well worth having a look at, ( in my humble opinion) maybe other members know better ?.
