c. Click Update.
d. Click on Current Status. Watch the Current Status: Channel-1/Channel-2 portion of the screen.
The “State” of each DID Modem should be “Waiting for Ring.”
10. Connecting CallFinder to PBX
Now that the Extension Ports have been configured (as FXS or FXO) you can connect the cables
between the CallFinder’s Channel 1 and Channel 2 connectors and the appropriate PBX port.
Remember:
(a) to connect a CallFinder channel to a PBX trunk port, the channel must be set to FXS;
(b) to connect a CallFinder channel to a PBX station port, the channel must be set to FXO.
11. Testing the Channel with a Call
a. From another phone (either from from another PBX extension or from an ordinary POTS phone
independent of the PBX), call one of the DID phone numbers that is active in the system. Dial the
DID phone number as you would from an outside line (it will not work to dial the number as if it were
an ordinary 3- or 4-digit extension of the PBX).
b. In the Current Status: DID Modem screen, the "State" field should change to "Waiting for Connect"
(briefly) and then to “Connected” (for the duration of the call) indicating that the voice connection to
the assigned PBX extension has been made. (The Current Status screen is updated automatically
each time you open the screen and every two minutes or so thereafter.)
c. If you observe both the "Connected" state and verify the presence of voice, then the CallFinder's
Channel has been configured properly.
If either of these is absent, see item #3 “What if the CallFinder channel doesn’t answer a call on the
DID line?” in the Troubleshooting section of this manual (page 81).
