Slight thread drift: if you are in Spain, dial 700500700 on any mobile or landline, Spanish lady tells you to dial the full number you want (i.e. access code*country code*area code*number you want) and after a bit you get connected over a VOIP. Cost is 4.6 cents a minute world-wide, any time of the day. Works to any land-line but NOT to any mobile. Extremely reliable, good clear connections every time.
