GAN is a web application which allows managing any type of national or international numbering with IN (intelligent network) or INGEO (geographical numbers) typology.

The numbering manager is in operator node, which makes possible treating the call prior to delivery to all the processes of the system functions.
Its separation from later processes (IVR and customer) permits the production of all the services required by the customer adding a contingency service (in the event of collapse of the IP connection), which operates via traditional telephony (DDIs). By using this process it is possible to eliminate the risk of connection failure due to problems of connectivity, collapse of the exchange, collapse of the physical lines (PSTN, ISDN, Primaries, etc.).
The GAN offers a wide range of functions allowing parameters to be specified for the distribution of incoming calls. This permits immediate response if required or in an emergency.
