Chapter 3 – CallFinder Server
Installation
This chapter shows you how to set up your Multi-Tech Model CF220 CallFinder.
The setup process entails cabling the CF220 unit and configuring the CallFinder software. The CallFinder
software resides on the CallFinder unit and does not need to be installed.
Prerequisite: Ordering the DID Line
To use the CallFinder system, you will need one or two DID (Direct Inward Dial) lines in your facility. You
must order the DID line(s) from your local telephone operating company (telco). A DID line allows one
phone line to be associated with multiple directory numbers. However, only one call can occur on this line
at any given time.
DID lines are sold in groups. For example, a telco in New York City might offer a DID line with a set of 20
directory numbers in the range of 212-555-4101 through 212-555-4120.
When ordering your DID line, ask the telco representative for these details about the DID service. These
details will be important when setting up your CF220 DID Adapter.
Parameter Value Required by
Telco
Number of digits used

You will need this information to configure your CallFinder (see step 8 on page 25).
