iZone Telecom provides Defne’s Collect Call Service which makes it possible for subscriber with a limited balance to make a call. With the help of the service, subscriber initiates a call but its cost is paid by called subscriber with his/her approval (reverse charging). With a 5-10% probability, called subscribers are likely to accept such call request. This helps call initiators to keep their balance unchanged.


To increase usage rate, call requests done by subscribers who are not allowed to make call due to insufficient balance may be routed.
