DISA / Call Through

Direct Inward System Access (DISA) i.e., CallThrough application is designed for companies who want to reduce the local and national interconnection charges involved in making calls between different networks and operators using 'dial-in' functionality.

The basic idea behind this PBX/IP-PBX 'Call-Through' solution is enabling authorized corporate users outside the office to call a pre-allocated telephone (DDI) number for obtaining a secondary dial-tone from within the organization's PBX/PABX in order to make calls using the organization's special low tariffs, and to capitalize on the direct connection to the different operators. As a result, the company saves up to 40% of the original direct call. Interested?
