Asterisk can only detect when a call has been placed.  Once the call has 
been made and the other end is ringing, is the calling extension showing up?

If not, I've seen this problem before with Asterisk 1.4.  You need to 
ensure that the following configuration items are set in sip.conf:-

    * call-limit must be set for every extension.  Usually set this to a
      large arbitrary number such as 100. (or 1 if you don't want
      another call to be received when the extension is on the phone)
    * notifyringing should be set to "yes".
    * If you're using RealTime, ensure you have both rtcachefriends and
      rtupdate set to "yes".
    * limitonpeers must be set to "yes" if you're using type=peer. (this
      is the most likely culprit since it's missing from the default
      config files)
