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. Three parameters relate to the DID line coming into the
CallFinder channel. 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 6.
Max DID Digits : the number of digits the CallFinder will receive from the telco central office on
the DID line.
DID Start : wink, immediate, or delay dial.
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.
PBX Extension Line Parameters
Extension Port : default = FXO (prevents damage from wrongly applied battery
and ring voltages)
Set as FXO when the CallFinder is to be connected to a PBX station port (a port that is
normally connected to a normal analog telephone).
Set as FXS when the CallFinder is to be connected to a PBX trunk port (a port that would
normally be connected to an ordinary POTS phone line from the telco central office.
Auto Attendant Delay : The Auto Attendant Delay value, x, determines how long the
CallFinder will pause before dialing on the PBX.
If the CallFinder channel is configured as an FXS port it will ring the PBX and wait x seconds
before dialing the proper extension after the PBX seizes the line.
Set x to be 1 or greater.
If the CallFinder channel is configured as an FXO port , x is the length of time that the
CallFinder will wait before dialing after the CallFinder itself has seized the line from the
PBX.
If set x to 0, the CallFinder must detect dial tone from the PBX before dialing. (The setting
of 0 can be used only if the PBX presents dial tone to the CallFinder.)
