The term Direct Inward Dialing refers to types of digit steered inbound call handling.These are DID, Both Way
DID, Dialed Number Identification service (DNIS) and Direct Dial In (DDI). The OfficeServ 7200-S supports the
types described below.
DID is an inbound only service where multiple telephone numbers are assigned, usually in blocks of twenty,
to a single circuit or small group of circuits. The DID service must be provided by ISDN/PRI trunks connected
to the OfficeServ 7200-S TEPRI/TEPRIa card.
Direct Dial In (DDI). This is the name given to the above three services when they are provided over an ISDN
PRI circuit.
The OfficeServ 7200-S has an option to select which MOH source is played to callers to a specific DID num-
ber.
DID Call Limits
This option defines the maximum number of simultaneous calls that the system will accept for each DID
number. Any call attempts after the Maximum Call (MC) count has been reached will be rejected and busy
tone returned.
DIRECT INWARD SYSTEM ACCESS (DISA)
Users can call in on specific DISA lines at any time, input a security code and receive system dial tone. Users
can now place internal calls or if permitted, calls using C.O. lines. The caller must have a tone dial phone and
know his/her DISA security code if DISA security codes/passcodes are turned on. DISA lines can be used as
both way lines or incoming only and may be allowed or disallowed for any of the 6 ring plan time periods.
The C.O. lines used for DISA must have disconnect supervision.The requirement to put in a DISA security code
can be disabled if desired.
DIRECT TRUNK SELECTION
Each station can be allowed access to or denied access from a trunk or trunk group by access code when LCR
is activated. When restricted, the station user must use a trunk key or a route key.
