Yes. You can call anywhere in the world. However please note two thing. Some numbers by default do not accept incoming calls from IP numbers, example toll free numbers in most of the countries. So calling to them will not work. Also some numbers in some remote parts of the world are high cost numbers, Example a Number is Guyana may cost 3 USD a minute, such a numbers are barred in our system. As a normal business person this should not impact to you. However if you have a need to call to such destinations then contact us, we have a separate product for such requirements.
