Direct Inward System Access (DISA)
If you are working externally and you have the need to make business calls, call your company and use the company PBX to make an external call to the desired party. You just pay the costs for the phone call to your company. The other costs will automatically be placed on your extension number or on a special project.
Note: To use the DISA function, your extension has to be authorized by the system administrator.
To activate the DISA function, you have to change the default password from “0000” to a personal one, see section “Change Password” on page 69.
You can also divert calls from your office extension to your external position, see section “Call Forwarding” on page 47. During the procedure you will be prompted for your password.
Enter the public number of your company,
followed by the DISA number.
Ask the system administrator for the defined DISA number.
Note: If want to register the call on an account number, you should use the Account Number procedure before you enter the external number, see section “Account Number” on page 83.
Follow the voice announcements.
Dial the digit(s) for external line access and the desired public number.
Note: Which digit to press for external line access depends on the configuration of the system.

Use the External Diversion function.
Procedure, see section “Call Forwarding” on page 47.
