Got this week off work for half-term and the phone is ringing pretty much every hour with cold-calls. I'm registered with TPS but caller display shows 'Unavailable International' quite often and the call starts with pause.. click... followed by distant voice pronouncing my name wrong. Normally I'm not in all day so I suppose I don't notice it. And I have several friends overseas so 'Unavailable International' could be one of them. Has anyone found the same thing? And, beyond 'not picking up the phone' have you found a good way to tackle it?
