I'd like to write a single-host CRM application, so I need to get the
CallerID information when a call comes in. I don't actually need a
PBX/softswitch. The user will have the FXO cards and a phoneset
connected on the same line, and will pick up the phone once the CRM
application has picked up the CID info and popped up a dialog box, etc.
Is it possible to just use OpenZAP to get this information, or must I
install Freeswitch and provide an IP phone as well?
