Ncid
From MythTV
NCID is short for "Network Caller ID". Modern phone systems provide Caller ID (CID) (also known as "caller line identification" (CLID)) information as part of the connection information when a call is in the initiation phase (when it is ringing), and is best described on the Wikipedia page.
NCID is an application that can be run on Unix-based systems, with the proper hardware, to capture the caller id information and make it available to clients over the network via a variety of means.
For use with mythtv, see Network Caller ID (NCID).
