CallFinder Operation

The CallFinder brings analog DID services to a key telephone

system or PBX that is not DID-enabled.

Prerequisite: Ordering the DID Lines

To operate the CallFinder system, you will need one or two DID

(Direct Inward Dial) lines in your office. You must order the DID

lines 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 10 directory numbers in

the range of 212-555-4100 through 212-555-4109.

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 unit.
