My sisters boyfriend in the US rings her when travelling by dialling his home number & automatically rerouting the call to Italy.
This worked fine until 6 months ago. Now she hears an American ringing tone when he calls,& when she picks up the line goes dead. If he keeps ringing, up to 15,20,times, she eventually hears her Italian ringing tone & then the call connects OK.
The US phone company say their router is working correctly as the call is connecting every time, & the problem must be in Italy. But the Italian phone company insist its not at their end.
Has anyone experienced a similar problem & can explain why this is happening?
