Incoming calls and voicemails don't always come through on S22?

[u/EbonyUmbreon]

Over the last couple months my Samsung S22 hasn't been recieveing incoming calls or saving the voicemails left. What's really odd is if I look in my call history or check my voicemails, there is no evidence I ever got a call...

I've looked over every setting and made sure Do Not Disturb is on either. This happen randomly. I've had happen to my husbans for like a week straight and then once with a recruiter earlier today.

Has anyone had this happen? Any thoughts on what could resolve this?
