call accounting Also called SMDR. A system used to record information
about telephone calls, organize that information, and
create reports. The information gathered usually in-
cludes what extension the call is coming from, what cir-
cuit is used for the call, when the call started, how long
it lasted, and the purpose of the call (usually what client
or project should be billed). Requires a computer, a disk
for storing data, and some software set up to monitor the
telephone calls made. A serial port must be dedicated to
it.
Caller ID Automatically identifies the caller Trunk line.
case-sensitive The act of differentiating between lowercase (a–z) and
uppercase (A–Z) characters. Amanda uses case-sensi-
tive passwords. AMANDA, Amanda, AMandA, or

you type these words at the DOS prompt, DOS treats
them as the same command.

nels and as large as 24 channels.
