I don't understand fully the variable presence_id, but i've tried a
few things without any success. If I use the following lines, the lamp
fill be enabled at the login for a few milliseconds.

<extension name="Queue Management">
  <condition field="destination_number"

    <action application="set"

${destination_number}"/>
