Awhile back, We posted on ESI’s Presence Management, which features a special device called a Presence Management Reader that has multiple functions.  It can act as a door phone, as security access for building personnel (using RFID-based security cards or fobs), and more.

We are pleased to announce that ESI has developed an IP version of its Presence Management reader.  We think this is exciting, because it allows for owners of all-IP ESI Communications Server phone systems to have Presence Management capability.  It also removes the limitation of 1,000 feet that exists with the original Presence Management reader (this was the maximum distance it could be installed from the phone server, or KSU).  In fact, a remote IP Presence Management reader can even be installed in off-site locations!  This does present interesting possibilities, like the ability to unlock a door remotely for example (after verifying the caller’s identity, of course, by talking to them via VoIP right through the reader itself).
