On Android, a variety of apps can record a call directly, unless the phone manufacturer blocks it. On iPhone, recording phone calls is blocked, period. The apps that do exist to record a call—and there are quite a few—have a workaround, but it will usually cost you.
I called customer support. They were not able to fix it and made it worse. Now it rings once instead of three times. They put in a service request and said it would be 1-3 days. Now they say 3 to 5 business days. I don't understand how something so simple could be such a major problem. I just wanted them to change the number of rings to at least 7. Disconnected the 1st of the junction boxes at top of door. Phone line rings after doing this so proves problem is in the home. I then ran a new wire pair to the NTE5, problem then came back, even with the pull out isolation port or whatever it’s called. Then wired direct to the back plate if that’s the correct term, phone starts ringing again.

This works for any call, live conversation, or endless Zoom call. On a second device—be it another iPhone, an iPad, laptop, or Android phone—open a voice-recorder app and hit record while you're talking. On iOS, the built-in version is called Voice Memos; we have a full tutorial on how to use it. Windows 10 has a built-in Voice Recorder. Android has a bunch of them.
