DH uses it all the time...
he has a skype phone attached to the computer (so it's like talking on a phone)...
he has local skype phone numbers in the US and other countries, so people calling him there are calling a local number...
the quality is usually very good...
sometimes he has to switch to a landline, but not often..
he speaks with people all over the world, both skype to skype and skype to phone (and phone to skype)..
it has saved thousands a month on our phone bill....(he's in international trade and so on international calls all the time)...
