PROTEI Call Back Server had been deployed by VIP OPERATOR in Macedonia

Сall Back technology provides a convenient and efficient alternative to the traditional scheme of providing mobile telecommunications services to roaming subscribers or to subscribers with outbound call barred. Using this system, instead of direct calling desired number subscriber sends an SMS or USSD request containing this number to the system’s service number. This request is processed by the Call Back server, which makes two outgoing calls – one to the caller and one to the number requested. Call Back Service is more profitable for the operator than the traditional connection. Thus, more flexible tariff rates could be provided for roamers allowing them to enjoy a more active communication while abroad.

PROTEI has been chosen by VIP OPERATOR as a Callback solution provider. PROTEI Call Back Server has been integrated with existing IT and telecommunication infrastructure of the customer. System software had been specially configured and adjusted to simplify integration and minimize changes to be done on Operator’s network elements and to enable flexible call charging. Special feature had been implemented to support Mobile number portability (MNP) service that must be provided by Macedonia operators according to National laws. Within framework of the project PROTEI also deployed USSD Center that may be used not only for the Call back service but as a base for many other USSD services also.

Thus, VIP OPERATOR has received efficient solution that allows to increase revenue through more flexible tariff rates for subscribers in roaming. Installation of PROTEI Call Back Server in Macedonia has again demonstrated flexibility of PROTEI solutions making possible fast and easy adaptation of any platform to the special demands of operator in any country.
