Show caller ID of 2nd line ringing

This one is probably a stupid simple question, and I’m likely not using the right terminology while googling. We have Yealink t46 phones with 3 line buttons. I’d like it to display who is calling the 2nd line when I’m on the first, the indicator flashes and I hear the call waiting, but no way to know who is calling that without holding the other call.

bump anyone have any tips here?

doh I’m a moron, it shows up at the bottom line of the screen. Don’t know how I missed it.
