Than my roaming free cellphone receives a call and I have a dialtone.

Calling fixed numbers will cost me around 7 cents per minute and mobile (europe) between 10 and 20 cents.

Works very well.
pbxes also has a webcallback feature where you can fill in any number where you are at that moment. You will be called on that number, type your pincode and receive the dailtone. This way your can receive a callback in your hotel, freinds house wherever.

I guess you can use the free roaming sim like ekit in Europe to trigger the callback, or it doesnt work on it?
