The advertise section of the conference configuration file allows you to generate presence events (advertisements) to services and subscribed parties via the FreeSWITCH event system. The idea is to set up permanent room names that generate presence events just like a phone or other device would. An outside program can then monitor whether a conference room is in use or not.

Advertise settings contains a room name in each element within advertise tags, as shown in this example:

<advertise> 
<room name="888@$${domain}" status="FreeSWITCH"/> 
</advertise>
