Best way to cheaply phone USA from UK landline

Vegastare

Hi 


I want to call US only once twice a year...with BT and last time I was offered an option for one month at certain cost...sorry cant remember amount and could cancel when needed as felt the friends and family monthly was not good option.

But friend here said you can sign up with other companies by putting pre fix in front for overseas calls
 Can anyone advise or recommend or suggest options

Have you looked at 18185?

Their rate for calls to the US is 2.5p/minute + 4p connection charge.
