9. Configuring the CallFinder’s Channels

The CallFinder’s channels direct inbound calls to their proper destinations.

a. In the CallFinder software, go to the Channel Configuration screen.

b. Under Channel Configuration: Channel 1, enter the values that match the characteristics of your

DID phone line in the fields provided. Four parameters relate to the DID line coming into the

CallFinder channel. Another four parameters relate to the PBX extension line to which the CallFinder

channel connects.

DID Line Parameters

Consult the telco supplying the DID line about these parameters. See the section “Prerequisite:

Ordering the DID Lines” on page 7 (and 23).

Max DID Digits: number of digits the CallFinder receives from the telco central office on the DID line.

DID Start: wink/delay, immediate, or reverse-on-disconnect.

Polarity: This refers to the DID battery polarity. This parameter must be set on a trial-and-error basis.

Signs of incorrect polarity:

(1) outside party originating call to DID number gets immediate busy signal after dialing;

(2) line suddenly disconnects just when call should go through.

DID Transmit Gain: This is the setting for the amplification factor (in dB) on the DID line.

This parameter has a range of -6 dB to 6 dB. The default value is 0 dB and, in general, this

should be the correct level. Alter the value only if the voice level as heard by the incoming caller

is unacceptable.
