DISA
Direct Inward System Access (DISA) allows users of the PBX to access their
communications functions from outside.
For example, a system-accredited salesperson on the road can make a local call
to the PBX, and be given access to analog or SIP trunks to make a toll-call to a
customer which will be charged to, and bear the Caller ID of the salesperson’s
company.
DISA Procedure
To maintain security, the procedure for using DISA is as follows:
•
User calls the system either at a specified extension or
dedicated number.
•
User is asked for, and enters the password.
•
System hangs up.
•
In one minute, the system calls the telephone number
identified in the Phone Number field of the DISA menu
(shown below).
•
The CallerID of the system is the one shown in the CallerID
field below.
•
The user is asked for the password once more.
•
Upon successfully entering the password, the user is given a
dial tone.
•
The user can place a call using the network’s normal calling
rules.
•
The called party will see the CallerID as entered in the
CallerID field below.
