Call Appearance Buttons
The row of translucent buttons beside the LCD screen on your Yealink phone are line keys. These buttons light up green when a call is active on that line.
Handling Multiple Calls
Answering a Second Call:
If you’re on a call and another call comes in, press the green illuminated line key for the new call.
This automatically places your current call on hold and answers the incoming call.
Toggling Between Calls:
Press the corresponding green line key to switch between calls.
Each press toggles you back and forth, placing the other call on hold.
Starting a New Call While on a Call:
Press the green line key for your current call to place it on hold.
Then select another line key and dial out to start a second call.
Creating a Conference Call
When two calls are active (one on hold, one live), a soft key labeled “Conf” will appear at the bottom of the LCD.
Press Conf to merge both calls into a single conference call.
