When enabling the presence service in CUCME, you are using the SIP methods of Subscribe and Notify to allow users the ability to see changes in the line state of phones.  The phone acts as a watcher using the subscribe method to get status updates from a directory number assigned to a phone that acts as the presentity.  CUCME will respond to the request and each time there is a status update for that DN or presentity, CUCME will send all watchers a notification message.  CUCME presence can be applied either as a BLF speed-dial assigned to a line button or as BLF call-lists that will support status notifications of a presentity in the directories or call log (missed, placed, received) of the phone.

I remember a time when I taught a class called CIT (Cisco Internetwork Troubleshooting) and there was a wonderful rule that made all the students sweat a little more and all the instructors give that old Dr.Claw laugh (From Inspector Gadget if you have no idea what I’m talking about).  Essentially it allowed the Instructor to do things that were really mean and evil and forced the students NOT to take the easy way out.  What was that rule?  When troubleshooting you may NOT use the command Show Running-Config or any variant of it.
