Call masking and Refilling relate to substituting an international call for a local one by redirecting an international voice call to a local GSM network. Often times, the receiving subscriber sees a local number or “Private Number” instead of the originating International number. GSM consumers as well as operators usually suffer considerable loss from the activities of the re-filing syndicate. They are fraud-related practices and anti competitive activities in the industry. REFILING is a form of inter connectivity fraud whereby one carrier tamper with the caller ID to disguise the number from which a call has originated.
