Presence State is a feature that was added in Asterisk 11, which
allows for more information to be captured about the state of a
user. There appears to have been a rather large oversight in the
implementation. There is currently no way to monitor the changes to
this information, meaning that nothing can take advantage of it in
any realtime manner over AMI.<br>
<br>
Given that the patch is trivial, and that presence state is not
otherwise useful for any outside system, I'd like to propose <a

for inclusion into Asterisk 11.
