I understand the inconvenience of calls going to voicemail and delayed notifications. To address this, first, check your call settings, network connection, and "Do Not Disturb" mode. Ensure your voicemail settings are configured for prompt notifications. If the issue persists, consider updating your phone's software and contacting your network provider for further assistance to resolve these concerns.

@ATTHelp , I reset the password and voicemails are still delayed.

@mrluckds, I have done all of your recommendations more than once. Thank you for taking the time.
