Hang up problem

Hey there Jager_OG,

That is a strange thing to occur, and we'd like to help however we can. Let's begin with learning more about what's happening, along with ruling out some possible causes:

1. When did this start to occur, and does it only happen with one specific contact?
2. Sometimes unexpected behavior can be resolved with a restart: Restart your iPhone
3. We see you have iOS 16 installed, but the latest version is iOS 16.5.1. You can verify this within Settings > General > About. In case you needed it, this link shows how to first back up, then update: Update your iPhone or iPad

Cheers!

Hello Jager_OG,

Thank you for that information. The best thing to do at this point would be to get in touch with Apple directly for further assistance at: Get Support - Apple

Cheers!
