Direct Inward System Access (DISA)

Direct Inward System Access allows cell phone and landline telephone users to call into your account and then initiate an outbound call using your systemโ€™s Default Caller ID.ย 

This feature of the system generally needs to be approved by VirtualPBX, as it can open you up to security risks and unexpected usage on your account if used maliciously. .

Using DISA


Mobile or landline users can now call into your main number. When they hear the main greeting play they can enter the extension number or menu option for Direct Inward Access if you set one up

They will then be prompted to enter the PIN.

Once the PIN is entered they will hear a dial tone, at which time they will want to enter the phone number they wish to call out to.
