+Auerswald Callnotifier for COMpact 3000
+***************************************
+
+Connects to the debug port of your Auerswald Compact 3000 telephony switchboard
+and listens for incoming calls.
+It will notify you whenever a call comes in.
+
+
+TODO
+====
+- multiple notification methods: XMPP, dreambox, notify-send
+- ldap name resolution
+- write a call list (who, when, how long)
+- filter/exclude by local target
+
+
+Issues
+======
+Ctrl+C does not send the disconnect command.
+This is a problem with PHP since pcntl_signal handling and blocking sockets
+do not work together. The signal will not be handled.
