Skype is free software that allows anyone to call another Skype user over the computer for free. They also have packages where you can call a real telephone number from your computer or get a number so other people can call your computer from a real phone for a small fee.
As I've mentioned here before, the government owned telephone company Etisalat had blocked all VoIP (Voice over Internet Protocol). Not sure how or why it's unblocked now, although it might have something to do with du - the brand new telecom company in Dubai that just started operating last month.
Are you ready for a fun fact, though? Apparently Etisalat and du have decided to charge the same prices for everything. Clever, eh? None of that crazy "competition" stuff. Because who really loses when there's competition? The businesses fighting each other for customers.
Anyway, download the Skype software and give me a ring! I'll be online ...
