The BELCOM-ISDN "PLUS" PABX system with Three-Channel Multiple Operator Technology was conceived to manage in an integrated, rational and controlled way, all company terminals: fixed telephones, mobile telephones, videophones, video conferencing, faxes and computers.

The mobile telephones integrated in the system behave as internal extensions of the company. They have their own extension number, personalized programmed restrictions of destinations allowed, access to the functions and services of the PABX system and the great advantage of being used in the whole coverage area of the GSM or UMTS networks (national or international).

All incoming and outgoing calls can be managed by the Financial Management software of BELCOM-ISDN "PLUS" PABX system, which allows the manager to have an absolute control (day, time, number dialled, cost of the call) of both fixed and mobile networks.

The communications costs can also be reduced in up to 80% since mobile telephones, once integrated in the PABX system, have access to the IMDEC Technology that chooses in each call, the route with the most economic rate. For instance: a mobile telephone call for a fixed network telephone, or for another mobile phone of any mobile network, doesn’t pay the high inter-networks tariffs but the most reduced tariff applicable inside the same mobile network.

This functionality has special benefits for Companies and clients of Hotels.
