1. Setting Directionality. In the PBX software, set the “Direction” parameter to Both Directions to allow both
inbound and outbound calling through the CallFinder.
2. Outgoing Calls. Set up the PBX with an access code for outgoing calls. “9” or “8” are commonly used as
access codes for special connections from a PBX.
3. Incoming Calls. For incoming calls, you must set additional parameters in the PBX software. Incoming CO
calls should be routed to ring a group of phones (in our example, we have a group of two members: extension
203 is an ordinary station port serving a POTS phone; 3009 is an extension connected through the Ethernet
Port and terminating in an IP phone). Alternatively, one could also route these incoming calls to an auto-
attendant.
4. Resulting Performance – The Inbound Calling Pool. By setting up the PBX as shown above, multiple
extensions will ring when a call comes into the PBX through the CF100 CallFinder. The first person to answer
completes the call, the ringing will cease, and the call cannot be joined by subsequent members of the hunt-
group who might try to answer the call.
