Product Description
The CallFinder
®
is a DID-to-analog telephony adapter. It brings analog DID services to a key telephone
system or PBX that is not DID-enabled. When equipped with the CallFinder, the phone system can route
incoming calls directly to end-user extensions. The CallFinder has two DID channels. Each channel is
connected to the telco DID line on one side and to the PBX/key system on the other side. A CallFinder
extension port can be connected either to a trunk port or to a station port on a PBX. The choice between
trunk port or station port connections depends on port availability, logging requirements, and/or on
whether it is necessary for incoming DID calls to be treated like outside calls instead of intra-PBX calls.
The CallFinder product consists of the hardware unit with pre-installed configuration software and
additional management software on a CD.
