I use skype with a skypein number, I also have an 0845 (UK local rate) number pointing to that. For my customers in other countries I intend to get an additional skype number that is local to those countries, but then we're only 1 hour time difference. You'd still get difficulty with that if you're UK and US, but then at least you'd have some overlap plus an answering machine.
