Audio glitching and cutting out during calls on iPhone 17 Air

"Audio glitching and cutting out during calls on iPhone 17 Air: I have a brand new iPhone 17 air and I cannot make a single call on it without having audio issues. The entire time I'm trying to talk to someone the sound is glitching and cutting in and out. I've turned the phone off and on and also have made sure it's updated to the latest software. This is extremely frustrating because it literally happens with every single phone call -- whether I'm on speaker or not. Anyone else having problems?"

New iPhone Sound Issues:

Who is the seller? I not Apple, then I'd say return it. If Apple, then chose to either return it, or get it serviced.

Returning this:

Perform as instructed here, including the iCloud logout: What to do Before you Sell, Give Away, or Trade in your iPhone or iPad - Apple Support

Getting this Serviced:

Set up a Genius Bar Appointment at your local Apple Store. There, it will be diagnosed, and you'll be provided with your options. You might want to see abut getting AppleCare with this, as it would cover your for hardware issues(to a certain extent).
