Why does this call failed issue continue to resurface every few months?

Why does this call failed issue continue to resurface every few months? I've written to this forum a few times regarding the issue. and I'm usually able to find a solution but the fact the issue continues to persist every few months feels problematic. And the issue has to do with someone calling my iPhone and it rings on my mac studio desktop and I go to answer the call on my desktop and it says "call failed. to make and receive calls, make sure iphone is nearby and on the same wifi network as this mac." my phone is right next to me and i NEVER have the wifi on, its always ethernet so why are the calls failing all of a sudden when I've fixed this issue at least twice in the past year. I went to the facetime application on my desktop just now and clicked the "enable wifi calls" button. (but why is it asking me to enable when I've been enabled in the past?)

Wi-Fi calling REQUIRES that the Wi-Fi be on. (it's NOT 'Internet calling' and the cellular carriers are the ones that demand Wi-FI be used exclusively.)

In general, packets going to the Internet are sent to the TOPMOST Working interface shown in the list of networks.

If Wi-Fi is listed second or later in that list of network interfaces, it will not be used for most data.

If you need to re-order that list, click the ellipsis below the list and choose Set Service order, which will allow you to drag the network interfaces into the order you desire.
