My phone is blocking my contacts randomly if I don’t answer it tells the contact they are blocked

Greetings Virginia1414,

Thank you for using Apple Support Communities. It seems like contacts are being told they are blocked. There may be some settings that could be causing this. We would recommend you use this article to help troubleshoot the issue.

Are you able to receive the calls after they are told they are banned?

Do you use any apps to filter or detect spam calls?

Do you have Silence Unknown Callers enabled?

"If the app determines that a phone number is spam, it may choose to block the phone call automatically."

Detect and block spam phone calls

Please don't hesitate to let us know if the steps resolved your issue or if you need additional assistance.

Take care.
