example, the call in number (Caller ID) is 123456789, MyPBX need to send
9123456789 to its trunk when call to this number. You should configure
123456789 as the call back number and add 9 before the callback is placed. You
can add “w” for analog trunks for some delay too.
6.7.5 DNIS Settings
DNIS (Dialed Number Identification Service) is a telephone service that
identifies for the receiver of a call the number that the caller dialed

Note: If DID is not configured here, all the calls via this trunk will show the DNIS
instead of the original caller ID
6.7.6 DISA
DISA (Direct Inward System Access) allows someone calling in from outside the
telephone switch (PBX) to obtain an “internal” system dial tone and make calls
as if they were using one of the extensions attached to the telephone switch. To
use DISA, a user calls a DISA number, which invokes the DISA application. The
DISA application in turn requires the user to enter a PIN number, followed by the
pound sign (#). If the PIN number is correct, the user will hear dial tone on
which a call may be placed. Obviously, this type of access has serious security
implications, and great care must be taken not to compromise your security.
