I've used UberConference to record interviews for assignments over the phone. It is the easiest way I've ever done interviews. All I need to do is put on my headset, give my subjects the number and time to call in, and then hit Record as soon as everyone's in the call.
UberConference does not have a time limit, compared to the free version of Zoom. My high school reunion committee decided to use Zoom because that's what they know, though I would have chosen Facebook Messenger before Zoom had I taken Zoom for a test drive. UberConference's free features are miles above what Zoom offers for free.
If you want a record of any conference call, UberConference can do it. If you're not near a phone, but you have a laptop or desktop, you can access UberConference without having to download an app. And if your team is all across the world, so long as they have internet access, they can call in without having to pay international calling charges.
