Yealink phones are very easy to configure for presence, to see the status of other phone users on your system.  We will update this guide in the near future with details on how to configure your additional line keys for presence and smart speed dials (speed dials that include current user status).  Also, keys can be configured to pickup other users calls if desired.  Handy if you need to cover for someone out of the office.
