<div>I am trying make presence module work with Kamailio. Right
now I am testing these modules: presence, presence_xml,
presence_dialoginfo, pua and pua_dialoginfo.</div>

<div>I had some success, the BLF is working only when the
monitored extension is calling. When the monitored extension
is calling, then the BLF changes its color (red). After end of
the call the BLF changes color to green.</div>

<pre><span style="font-family:arial,helvetica,sans-serif">Second question is about BLF and offline state. I can not found anything in RFC, there is no offline state, no way to turn off the BLF lamp from green to OFF.

BLF is about dialog states, not user (device) states, so it is about
being in a call (busy) or or not. Not to get notifications about it,
you should unsubscribe for dialog event.<br>
