Direct Inward System Access (DISA)

The DISA feature allows incoming CO calls to access a specific destination, bypassing the
attendant station. Unlike DID, there is no digit conversion in DISA.
On accessing an incoming CO Line, the system will give the pre-recorded VMIB announcement
or dial tone. The caller then is able to dial additional digits to access their desired destination on
the system.
Set DID Digit Mask by pressing #1**. The first digit 2 is ignored and second digit 6 is
converted to 1 and the last two digits are bypassed.
Verify that DID Digit Receive Number is set to 3 at PGM 146.
Set DID Conversion Type as 2 (using Flexible DID Table) at PGM 143 and press FLEX
4.
Program Flexible DID Table as shown in the PGM 231 Flex DID Conversion Table.
Destination of calls handled can be Station, Hunt group, VMIB announcement, Drop
after VMIB announcement, System Speed, Internal Page, External Page or,
Internal/External/All Call Page.
If the call is not answered or the number was invalid, the call is routed by DID/DISA
Destination.
DID calls to a busy station can be placed on a waiting stage according to admin
programming to KTU and SLT.
