Hello and welcome!
How old is your quaker? And we would love to see a picture. We even have phot of the month contest.
Young quakers Bob for attention and food from their parents.
Newly weaned may bob in a new home as they can revert and need a few comfort feeding.
This can carry over to adults, my old girl Penny bobs when excited and when I'm talking to her. My other 2 Bob if I Bob to them or I'm handing them a treat.
Quakers are very prone to screaming. But many species want to scream when we are on the phone. They do know we aren't talking to them and they want our attention.. you can try to recondition this response to the phone. If you know of a phone or video conference time, try sbd set her up with a snack or activity like foraging fir a snack, or encourage a bath. Right after a bath they are usually quiet for a half hour or so.
And do lots of fake phone calls and give treats for being quiet , and keep redirecting and interrupt when she makes noise. Trying fir a pattern of being quiet.
And because they like to be vocal they make noise when we make noise. So try and get them to say a word or whistle or as mentioned quieter noises. And reward those lavishly.
A quaker with not enough to do will give themselves the job of screaming.
They do need a lot of one on one and out of cage time. You can set them up with their own stuff near you.
Like this ,
I'm often posting how I use ceiling hooks abd heavy weight fishing line to create what I call an aerial gym. I attach foraging stuff, stuff to chew, and treats to find to keep my flock busy. So now I will share examples to inspire you. Hopefully you all will share yours to inspire me too! this...

And you can try and pattern quiet times. I worked very hard to have a quiet cage time after lunch for an hour or two. I started with just short cage time with treats like 10 min and got them back out before they would scream and slowly made the time longer. Untill it became a routine and pattern. But thus works because they have lots of out of cage time ( I'm home so 6-8 hrs out) and they get at least an hour of cuddling can be split up during the day.
They also forage and eat lots of veggies morning and evening that takes up a good hour of time in morning and evening.
I have not found that ignoring a screaming quaker helps anything. Instead I work to prevent, redirect, interrupt and random praise and treats only when quiet.
