Yes, it is possible to silence someone’s calls on an iPhone without blocking them. This can be useful in situations where you still want to receive messages or notifications from the person, but do not want to be disturbed by their phone calls.

Here are the steps to silence someone’s calls on an iPhone:
- Open the Phone app on your iPhone.
- Tap on the Recents tab at the bottom of the screen to view your call history.
- Find the person you want to silence and swipe left on their name or phone number.
- Tap on the “More” button that appears.
- Tap on “Block this Caller” and then confirm your selection.
- Next, tap on “Block Contact” to silence their calls without blocking them.
- Finally, tap on “Done” to save your changes.
After completing these steps, calls from the selected contact will be silenced and sent straight to voicemail. However, you will still receive messages and notifications from them, and you can still call or message them yourself if you choose to do so.
It is worth noting that the steps outlined above may vary slightly depending on the version of iOS that you are using, as the settings and menus can change with each update. However, the general process should be similar regardless of your iOS version.
In addition, keep in mind that silencing someone’s calls without blocking them may not be an effective solution for everyone. If the person is persistent and continues to call you even after being silenced, it may be necessary to block them entirely in order to protect your peace and privacy. Additionally, if you are receiving unwanted or harassing calls from someone, it may be necessary to take further action such as reporting the behavior to your carrier or local law enforcement.
