BLF on our receptionist phone no longer displaying properly on registration status of phones - they always display green even if the phones are not registered e.g. physically disconnected from the network. It should display orange. However, they're displaying on active calls - flashing red when ringing and solid red when answered.

Can anyone give me an idea how to attack this problem? Just a hint. I see the databases sip_subscriptions, sip_registrations, sip_presence, sip_dialogs, etc.

Which important Events to watch?

Just a hint. Thanks.
