PBX Direct Inward System Access

An external caller can access internal pbx features on certain CO lines by keying in a special code.

The PBX answers the incoming call with dial tone, and the caller enters the access code (if required) and destination extension number or routing code.

The basic idea behind this DISA /Call-Through solution is enabling authorized corporate users outside the office 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.
