That doesn't seem to make sense. If they called him then they're paying for it on their end and now he's paying for it on his end too? If someone receives a call on a landline from the UK they aren't billed for the call. It merely terminated there. The person placing the calls bears the weight of the bill. If this were true, according to the per minute charges on the AT&T international country calculator, someone could slam you for as much as $5 a minute but simply misdialing to your phone.
