+  The FB_CALLMONITOR module connects to a AVM FritzBox Fon and listens for telephone
+  events (Receiving incoming call, Making a call)
+  <br><br>
+  In order to use this module with fhem you <b>must</b> enable the CallMonitor feature via 
+  telephone shortcode.<br><br>
+  <ul>
+      <code>#96*5* - for activating<br>#96*4* - for deactivating</code>
+  </ul>
+  
+  <br>
+  Just dial the shortcode for activating on one of your phones, after 3 seconds just hang up. The feature is now activated.
+  <br>
+  After activating the CallMonitor-Support in your FritzBox, this module is able to 
+  generate an event for each call.
