1.1. Overview

   The pua_mi offers the possibility to publish presence
   information and subscribe to presence information via MI
   transports.

   Using this module you can create independent
   applications/scripts to publish not sip-related information
   (e.g., system resources like CPU-usage, memory, number of
   active subscribers ...). Also, this module allows non-SIP
   speaking applications to subscribe presence information kept in
   a SIP presence server.

   The following modules must be loaded before this module:
