Hello, I have 4 phones, 3 will join a conference room called 'myConf' and I'm trying to get BLF status for this conference on the fourth phone, which will eventually join the conference by pulling the related BLF button. On the phone I want BLF I set to monitor the status using 'sip:myConf@192.168.0.252' (which works when monitorning a normal sip user), then I tried the followings: Set the <advertise> field like this <advertise> <room name="myConf@$${subdomain}"/> </advertise> in conf/autoload_configs/conference.conf.xml but this doesn't work. Set: <action application="set" data="presence_id=myConf@${domain_name}"/> in my dialplan before setting up the conference, still doesn't work. Issuing: presence in myConf@192.168.0.252 on-the-phone "on the phone" from fs_cli, but still doesn't work. The only thing I got working is to manually send the event using ESL like this: event = freeswitch.Event('PRESENCE_IN'); event:addHeader('proto', 'sip'); event:addHeader('from', 'myConf'..'@'..'192.168.0.252'); event:addHeader('login', 'myConf'..'@'..'192.168.0.252'); event:addHeader('event_type', 'presence'); event:addHeader('alt_event_type', 'dialog'); event:addHeader('Presence-Call-Direction', 'outbound'); event:addHeader('state', 'active'); event:addHeader('unique-id', uuid); event:addHeader('event_count', '1') event:addHeader('answer-state', 'confirmed'); event:fire(); In this case the BLF correctly lights up, but when the phone issues a new "SUBSCRIBE" request the BLF is cleared. Wrapping up: is there a way to use BLF to monitor the status of a conference call from a phone not invited when the conference is set up?
