DISA

Direct Inward System Access, or DISA, allows users to dial into the hosted PBX from an outside line, and make outbound calls that will display Caller ID information from a DID within their office.

A DISA is typically used in routing scenarios, such as:

• Unannounced options in an Auto Attendants
• Call Routing Inbound Dialing Rules for an Extension

The number of DISAs that you can create is limited only by the number of assignable DIDs within your PBX.

DISA permissions are enabled by default for these User Types:

• Reseller Admin
• Customer Admin

   The customer's Phone Numbers screen displays.
2. In the menu panel on the left, click the DISA menu option.
   The DISA screen displays. The DISA list is sorted ascending by DISA number.
3. Click the New DISA button.
   The New DISA screen displays.
