DISA - Direct Inward Station Access

Overview

DISA is used to allow people from the outside world to call into your PBX and then be able to dial out of the PBX so it appears that their call is coming from the office, which can be handy when traveling. You can set a destination in an IVR that points to the DISA or set a DID to point to the DISA. Make sure you password-protect this to keep unauthorized people from dialing in and using your PBX to make calls.

SECURITY NOTE

Please note, this is like someone sitting in your business making calls. Every effort should be made to hide your DISA from the public and secure it. Leaving it exposed could lead to toll fraud and high phone bills.
