How to Block A Number From Leaving A Voicemail

In today’s digital age, managing our communication preferences is more important than ever. With the rise of robocalls and spam messages, it can be overwhelming to deal with unwanted voicemails from unknown numbers. If you’re tired of receiving pesky calls or voicemails from specific individuals, this article will guide you through a step-by-step process on how to block that number.

Understanding Phone Voicemail Systems

Before diving into the blocking process, let’s briefly explore how phone voicemail systems work:

  1. Voicemail Recording: When an incoming call goes unanswered (either due to no answer or busy), your phone records the caller’s message as a digital file.
  2. Message Length: Typically, standard messages have a 3-5 minute duration.
  3. Memory Management: Most voicemail systems have limited memory space, with newer calls automatically overwriting older ones after storage is filled.

Section 1: Using Your Phone’s Native Functionality

Option 1: Block Numbers on iOS Devices (iPhones/iPods)

On your iPhone, navigate to Settings > Phone > Call Blocking & Identification. Enable the feature and you’ll see “Block Contacts” at the bottom. Add the unwanted number from there.
