The DISA module allows any user or caller to get access to certain features or even make an outbound call through the IP-PBX and reduce call costs. As soon as the caller reaches the Direct Inward System Access (DISA), an invitation to dial tone will be heard.
Because DISA is like using an internal extension to place an outbound call, it is VERY IMPORTANT to restrict the access by using a set of passwords. We can reach the DISA feature from Inbound Routes or from an IVR.
To set up DISA, we must follow these steps:
Add a DISA name: The name of the DISA we want to create.
Enter a PIN: The password or passwords allowed to use this DISA. If we want to use a set of passwords, we enter them here separated by a comma.
Set the Response Timeout: The amount of time in seconds to wait if the dialed number gives us a response before the IP-PBX hangs up our call.
Enter the Digit Timeout: The amount of time in seconds to wait between entering digits before the call is hung up.
