In order to get the most from thischapter, you will want some experience with a programming or scriptinglanguage such as bash, PERL, or C. Any language should do as Intercom'scallouts are general.</P><P>Intercom provides a way by which a shell command can decide whatIntercom should do on a certain event. This allows the user to do things assimple as playing a sound when an Incoming call comes in or as complex asimplementing time restrictions and blacklists. This chapter describes thesemethods and includes examples whenever possible.</P><DIVCLASS="NOTE"><P></P><TABLECLASS="NOTE"WIDTH="100%"BORDER="0"><TR><TDWIDTH="25"ALIGN="CENTER"VALIGN="TOP"><IMGSRC="/usr/share/sgml/docbook/stylesheet/dsssl/modular/images/note.gif"HSPACE="5"ALT="Note"></TD><TDALIGN="LEFT"VALIGN="TOP"><P>The implementation should be fairly easy for any shellprogrammer to understand; however, I am a programmer and not a technicalwriter.

Bycommand, I refer to an Intercom command and not a Unix shell command. Hooksare administered through the <BCLASS="COMMAND">hook</B> command and areautomatically saved with the <BCLASS="COMMAND">save</B> command.</P><P>To add a command-hook, you pass the event type and the command toexecute to the <BCLASS="COMMAND">hook add</B> command. The command you specifywill be executed whenever that particular event is triggered. The currentlydefined event types are as follows.</P><P></P><UL><LI><P>call_incoming - Triggered on an Incoming call. At the pointof the trigger, Intercom is ready to either accept or reject the call unlessa previous hook of this type has changed the state</P></LI><LI><P>call_outgoing - Triggered when an outgoing call is placed. The event is triggered after a connection to the remote host has succeededbut before the call is actually answered or rejected by the calledparty.</P></LI><LI><P>call_connect - Triggered just as a call is connected. Thisevent is triggered both when we are the caller or the callrecipient.</P></LI><LI><P>hangup_lc - Event which is triggered when our end terminatedan established call.</P></LI><LI><P>hangup_rmt - Triggered when the remote party hasdisconnected a call.</P></LI></UL><DIVCLASS="NOTE"><P></P><TABLECLASS="NOTE"WIDTH="100%"BORDER="0"><TR><TDWIDTH="25"ALIGN="CENTER"VALIGN="TOP"><IMGSRC="/usr/share/sgml/docbook/stylesheet/dsssl/modular/images/note.gif"HSPACE="5"ALT="Note"></TD><TDALIGN="LEFT"VALIGN="TOP"><P>You can have more than one hook for an event type.
