I get the squares, green available, red on a call, etc. However, is there a guide as to what the rest of the icons mean? I have some users with a phone icon and it seems random who has it as just one example.
Please note that the phone icon is usually displayed when system extensions are displayed like Queues, Digital receptionists or ring groups.
Other icons like a mobile phone is displayed when a contact has its mobile phone stored or a house icon will appear when the house number of a contact is used.
