Using Multiple ISDN Numbers
You may have multiple ISDN numbers from your ISDN service provider. You can
map these numbers to the AA (Auto Attendant) and directly to extension
numbers.
Note: Use AA if you do not have multiple ISDN numbers.
AA (Auto Attendant)
After calling the number, the caller is prompted to dial the extension number.

Auto Attendant (AA) Example
DDI (Direct Dial In)
DDI (also called DID, Direct Inward Dial) is a feature that maps a public number to
an extension number. DDI enables a caller to call an extension number without
going through an operator. When people give out their contact number and say it's
a “direct line”, often what they mean is that it's a DDI number.
For example, your company has 10 phone numbers (555-123456~555-123465).
You can choose 555-123456 to be the directory number (the company’s
representative phone number) and map the others to extensions using DDI.
