hi @tmbpoole
You can set up busy lamp fields (BLF) on your supported Yealink desk phones to monitor other Zoom Phone users as to whether these users are on their Zoom phone. Please check to see what your Yealink desk phone models support. Setting up BLF is easy. Please see Zoom support articles below.
The Quick Start Guide may be useful to users and admin.
Zoom Workplace desktop and mobile apps will show Zoom presence complete status, i.e. in meeting, on call, etc.
