Highlights
DID Enabler. The CallFinder DID adapter allows non-DID
enabled systems to support auto-call routing, eliminating
the need for a receptionist or auto-attendant menu dialing.
Direct Inward Dialing (DID) allows a PBX or key telephone
system to use a block of telephone numbers, via two DID
lines, for direct dialing to extensions. Callers simply dial
a typical telephone number (no special procedures are
required). The CallFinder DID adapter automatically converts
the DID phone number to analog DTMF tones and delivers it
to the PBX to ring the called party's extension.
The CallFinder DID adapter can interface to most call
processing systems capable of detecting ringing, loop
current and providing on/off hook control. It supports two
DID circuits that can be programmed to support wink-start,
immediate-start or delay dial service types. In addition, it
offers answer supervision and passes audio notification, from
the switch, back to the central office (audio ringback and
busy).
Loop Start/CO Port Connections. The CallFinder DID adapter
can also connect to the PBX/KTS via a Loop Start/CO port
(FXO). With this setup, an answering device, such as an
Auto Attendant, is required. When a DID call is received,
the CallFinder DID adapter will check its table, ring into
a Loop start trunk, and deliver the extension number via
DTMF tones. The PBX delivers the call directly to the enduser automatically bypassing the auto attendant menu. In
addition, because it is delivered as an outside call, the user
now has the ability to offer call detail reports through call
accounting software.

Analog Extension/Station Port Connections. If you don't have
any available CO ports, the CallFinder DID adapter can also
connect to the PBX/KTS via an analog extension/station
port (FXS). When using this type of connection, the PBX will
deliver the call to the end-user as an internal call. Typically
the user would program the PBX/KTS to display "DID Call" to
the other station phones.
