User level: Level 1 (4 points)When I make calls from my house my phone doesn’t seem to use the WiFi, but the really poor signal we have here. What’s the problem? I have checked the phone but can’t see an issue. Is it a known issue with iPhone 16

It is not a problem with iPhone 16, because if it was there would be thousands of posts about it. Wi-Fi calling is a carrier service, so if you have problems with it you need to contact your carrier.
One possibility:
Do you have a 3rd party VPN installed, even if you are not using it? If so, delete the VPN profile in Settings/General/VPN & Device Management/VPN, then restart your device. Don't just turn it off; delete the profile.

When you say you checked the phone, did you check to make sure WiFi calling is set to On? Are you sure you have a strong WiFi signal? Are you sure your cellular carrier supports WiFi calling? If you can please offer more detail, we may be able to offer assistance.
You say this is a "known issue with iPhone 16." I spend a lot if time in the forums answering questions and have not seen that. But that is besides the point since your tag lines say you have an iPhone 7.
