The CallFinder® DID adapter allows a non-DID enabled PBX or key telephone system to support analog DID services through standard analog station or CO port connections. It enables the phone system to directly route incoming calls to end-user extensions. The CallFinder DID adapter has two DID ports and two programmable
FXS/FXO ports and offers a web interface for system configuration and management.

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 end-user 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.
