Grandstream Networks GRP2615 Sip Presence Guide

SIP Presence Guide
P a g e | 6
OVERVIEW
The SIP Presence feature improves the users monitoring on the UCM6xxx and extends the VPKs/MPKs
utility on end points. A Busy Lamp is limited in its usability to phone line status, it can provide line connectivity
and calling status, but something more informative is required.
SIP Presence can provide ability to be informed about user’s extension when it’s offline / online like a Busy
Lamp, but that’s just the basis. Users can also use Presence to share their status, and tell the others that
they are out of office / On Chat / Do not Want to Be Disturbed, and so on.
This guide will be explicating the SIP Presence feature, and the user should have the UCM6xxx and end
points supporting Presence Watcher features:

The prerequisites in our scenario are as follow:
 UCM6xxx with firmware version 1.0.14.23 or higher.
 A phone supporting presence watcher feature see [SUPPORTED DEVICES] section.
