I need more complicated presence management in my system, so I would like to change blf status in VoIP terminal on my own. I tried with sendevent via event socket: sendevent PRESENCE_IN Answer-State: ringing proto: sip from: 5000@ubi2.pl rpid: unknown event_type: presence alt_event_type: dialog presence-call-info-state: progressing presence-call-direction: outbound The problem is that body part of SIP Notify message does not contain status and IPPhone doesnot change BLF LED: <?xml version="1.0"?> <dialog-info xmlns="urn:ietf:params:xml:ns:dialog-info" version="0" state="full" entity="sip:5000@ubi2.pl"> </dialog-info> When making call with properly set presence_id, Freeswitch sends SIP Notify message with correct status info: <?xml version="1.0"?> <dialog-info xmlns="urn:ietf:params:xml:ns:dialog-info" version="2" state="full" entity="sip:5000@ubiquity.pl"> <dialog id="01ca4d76-3e20-4167-b33c-f134f55b365d" direction="recipient"> <state>ringing</state> </dialog> </dialog-info> It seems that IPPhone needs this state info to change BLF LED button (yealink T21PE2) Is there any way to send NOTIFY message with state info without really making a call ?
