I just started a Job at a huge hospital complex in IT. I had to do all kinds of training. Because the onboarding is the same for everyone. So I was learning about medication plans and all kind of things I dont need.
Everyone also had to learn about IT security and stuff like that.
I was more engaged when a guy was talking about the paper archives than when I was learning about the IT security implemented here.
And I LOVE learning about it. But still almost fell asleep.
It wasnt the topic, it was the person presenting. The archive guy was so excited about the archives and had so much energy it just took me with him and months later I still know the sorting system they are using and whatnot.
The IT guy almost fell asleep himself and he somehow managed to present something like hashing in a way that would get me disinterested in IT as a whole, and I have been working and studying in IT for 15 years now.
I know phone service is boring, but maybe you also show with your voice and body language that it is boring? So they get disinterested. Maybe you can present some interesting facts? Get a joke in sometimes? Try getting stupid puns in so they can remember stuff better? Be a little excited. Maybe joke about how exciting this boring field is.
If still nothing happens, then ask management if maybe you can drop this since nobody is listening.
I had someone who showed me the server farm and usually they are asked to show us at least 4 hours and he told me it will be just 10 minutes because usually people dont care.
He started out really bored and was expecting me to fall asleep, but since I have never seen a server farm that huge I got excited and was asking questions all the time. I had to lead HIM and told him what I wanted to see. After an hour or so he actually enjoyed telling me stuff and he was able to keep me engaged and get interesting info out while teaching me everything and more I needed to know. After 6 hours I was actually sad it ended and since them he started to get people to stay 4 hours since he enjoyed it again and kept people interested with nice information and showing them around.
People enjoyed it so much, that people who started like 3 year ago actually asked him to have another tour, since last time they only sat in a room for 10 minutes and he told them just what they had to know.
Maybe something to think about.
You can do it and I bet you can find something to get people engaged. At least long enough to convey information
