DISA
DISA (Direct Inward System Access) allows someone calling in from outside Yeastar S-Series to
obtain an “internal” system dial tone and make calls as if they were using one of the extensions of
S-Series.
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 key (#). If the PIN number is
correct, the user will hear dial tone on which a call may be placed.
Please check the callback configuration parameters below.
