    Predefined Extension Names

Asterisk uses some extension names for special purposes:

    * *i <http://www.voip-info.org/wiki-Asterisk+i+extension>* : Invalid
    * *s <http://www.voip-info.org/wiki-Asterisk+s+extension>* : Start
    * *h <http://www.voip-info.org/wiki-Asterisk+h+extension>* : Hangup
    * *t <http://www.voip-info.org/wiki-Asterisk+t+extension>* : Timeout
    * *T <http://www.voip-info.org/wiki-Asterisk+t+extension>* :
      AbsoluteTimeout
    * *o?
      <http://www.voip-info.org/tiki-editpage.php?page=Asterisk+o+extension>*
      : Operator
