[Freeswitch-users] Using OpenZAP + FXO card just to get CID info?

[Fred]

Hello

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?

Thank you.
