Direct Inward System Access (DISA): A 2025 Guide

Direct Inward System Access (DISA) is a telephony feature that allows authorized users to access a business phone system remotely. With DISA, users can make outgoing calls through the company’s phone lines, even when they are outside the office. It enables remote or traveling employees to maintain the same level of professionalism as if they were in the office.

Direct inward system access provides users with a secure way to connect to the phone system. It typically requires authentication, such as a PIN or password, to ensure that only authorized individuals can use the system.

The process for direct inward system access starts when a user dials a designated phone number connected to the business phone system. After dialing, the user is prompted to enter a secure PIN or password for authentication.

Once authenticated, the system grants access, enabling the user to make outgoing calls through the business phone lines. These calls appear to be made from the office, ensuring professionalism and consistency.

Direct inward system access provides businesses with a secure and flexible way to manage communication. DISA allows remote employees to make professional calls using the company’s phone system for enhanced control and improved efficiency.
