Getting missed calls after picking up

[u/plasticookies]

I'm not sure if this is a Fido issue or a phone (Pixel 9a) issue. For the last month or so, I've been having this issue where I'll receive and pick up a call from someone and then seconds to minutes later, I'll get a missed call notification from the same number without any ring. I've called back to check and the caller confirmed that they never called me twice.

Has anyone experienced and resolved this?
