Ultimate Guide to Voicemail: Setup, Features & Best Practices

“Voicemail is dead”…that’s the corporate rumour. But voicemail isn’t dead, it’s just gotten a serious upgrade. These days, voicemail is smarter, faster, and more crucial than ever for maintaining control over your communications.

If you own your number, it’s time to stop treating voicemail as a chore and start treating it as your 24/7 assistant. 

Here is your ultimate guide to setting up voicemail in 2025, from the latest features like transcription to step-by-step setup guides for any device.

How Voicemail Has Gotten Better 

At its core, voicemail is simple: it’s the phone feature that lets a caller leave a recorded message when you can’t pick up. Think of it as your essential safety net; it guarantees you capture vital information instead of letting a connection (or potential client) disappear.

When your line is busy or unanswered, the call automatically forwards to your dedicated voicemail server. It plays your voice greeting, records the message, and stores it. 

If you’re struggling with an old system or dealing with complex, carrier-specific setup rules, often the quickest way to get reliable, straightforward voicemail features is to buy a new number that includes voicemail right from the start.

The main difference now is access. You’re no longer stuck listening to messages in sequence; phone and voicemail platforms can manage them instantly via an app, email, or text.

How the Cloud Works With Voicemail 

Today, voicemail lives in the cloud, and that’s where the power shift happens. 

These days, technical advancements and leveraging AI makes managing messages incredibly efficient, especially for busy entrepreneurs and small teams.

Voicemail Transcription (Voicemail to Text)

This is the biggest game-changer. Voicemail transcription automatically converts the audio message into text, which you can read instantly.

Voicemail to Email (Straight to your Inbox!)

Some companies have a feature that routes the transcribed text (and often the original audio file) directly to your email inbox, or as a text message. 

Voicemail with Auto-Attendant Menus

“To leave a message for Sales, press 1…” Take it a step further and allow your callers to reach multiple departments, staff members, etc. by using a phone management platform with auto-attendant menus. NumberBarn’s basic call forwarding plans include auto-attendant menu features allowing your callers to choose from up to ten different forwarding options. Business Line gives even more advanced menu functionality so you can set up different voicemail greetings for different times of the day (like an after-hours voicemail greeting, etc.).
