Ask HN: VoIP for Podcast App

I'm thinking about an app to create podcasts simply over the phone.

From what I see there's a bunch of interesting tools to make podcasts, but in the end they all require some sort of setup on both sides, or access to a laptop, or else.

Maybe I'm missing something, but why can't there be an app where you simply call your invitee and record the call that will become the podcast itself? Then can be post-produced, but the core would be to simply record the call.

I want to start making podcasts for my DTC brand interviewing founders of burger joints, but, being a tech guy for me it's easy, on the other side a burger joint guy may not be that tech savvy.

Make sense?

I'm interested in discussing ideas, and collaborations with anyone who'd be interested in working on this with me.
