Introduction - Grandstream Networks UCM6 Series Manual

INTRODUCTION

The UCM6XXX is now offering the ability to subscribe to extensions state, and to be informed about the
current presence status of a coworker phone extension. So far, the users can use the BLF (Busy Lamp
Field) to check the phone communication state, and will be advertised of every state change (Idle / Ringing
/ Connected), the added value of SIP Presence is to keep the user advertised on the monitored extension's
current general state as well (Available / Busy / DND ...).
SIP Presence is one of the new added features on the UCM6XXX series, allowing a user to publish his/her
presence state, this state can be predefined and known state (Available / Busy / Unavailable ..), or a custom
state that can take any format, and can be customized by the user. The monitoring extension can subscribe
to the presence status and be updated about any status change.
This guide describes the utility and steps for configuring the SIP Presence on UCM6xxx, as a main feature
when the user wants to be informed about other extensions' status.
Note: UCM6xxx includes UCM620x, UCM630x and UCM630xA series and UCM6510.
