5. When doing more than one box with caller ID, you must choose ONE box to be the SERVER. For all the OTHER boxes you must edit /etc/rc.d/rc.sysinit.author and comment out the line that starts ncidd (the server process). You must ALSO edit the /var/hack/etc/ncid/ncid.conf file on each of the client boxes (line 11) to set Host to the IP address of the SERVER box. After making these two changes for each CLIENT box, you must reboot the box. Only the single SERVER box needs a phone line connected for ALL boxes to get on-screen caller-ID. My problem was that my ncid.conf file had the wrong ip in it. All is well now!
