fonmon is a remote phone monitor for isdn4linux.
It includes a server application for your
ISDN-enabled computer (e.g. an ISDN gateway) and a
client for your workstations (Linux and even
Windows). You can easily monitor all incoming
calls through your network with various clients,
with features like highlighting, logging, and
number/name exchange. The server won't run on a
machine without an ISDN card in it.
