Misc. Dialplan Tools presence
From FreeSWITCH Wiki
Sends an event of either type PRESENCE_IN or PRESENCE_OUT. Currently, this function is not very useful in conjunction with sofia. This does not affect the presence of hook state for use with blf either, but sending an event that expresses the user's hook state does.
Usage:
presence <user> <rpid> <message>
Examples:
presence in|1000@xxx.xxx.xxx.xxx|dnd|'Do not disturb.'
presence out|1000@xxx.xxx.xxx.xxx|unavailable|'Currently out for a pot of hot coffee.'
