How to Set Up Voicemail in 3CX

Setting up voicemail on 3CX is a simple process that allows users to receive and manage missed calls directly from the mobile app.

If you want to know how to set up voicemail on 3CX phone systems, follow these simple steps.

Step 1: Open the 3CX Mobile App

Launch the 3CX application on your Android or iPhone device and log in using your extension credentials provided by your system administrator.

If you are setting up the app for the first time, make sure your business phone system is already configured properly.

Step 2: Access Your Voicemail Settings

Inside the application:

Open the keypad
Dial your voicemail number
Enter your voicemail PIN
Access voicemail options from the menu

The default 3CX voicemail number is usually (3CX’s own guide confirms 999 as the system default, followed by your PIN and #, and notes that the administrator can change it):

999
or 9999 depending on your configuration

This is one of the most searched questions related to 3CX voicemail number settings.

Step 3: Record or Upload a Voicemail Greeting

One of the most important parts of the setup process is configuring your 3CX voicemail greeting.

After accessing the voicemail menu:

Press 9 for voicemail options
Press 8 to change your greeting
Record your message
Save the greeting

Your 3CX default voicemail greeting can also be replaced with a professional custom greeting for business calls. In V20 the easiest way is the Web Client or the Windows softphone: click your avatar, open Settings → Greetings, and upload a file, record from your PC microphone or from your IP phone, or fall back to the default greeting — separately for each status.

A professional greeting should include:

Your name
Company name
Alternative contact instructions
Expected callback time

Example:

“Thank you for calling ITS UAE. I am currently unavailable. Please leave your name and number, and I will return your call as soon as possible.”

Step 4: Enable Voicemail Notifications

To avoid missing important messages, enable voicemail notifications from the application settings.

This allows users to receive:

Push notifications
Email alerts
Message indicators

Many businesses using cloud PBX systems rely on voicemail alerts to improve customer response times. 3CX notifies you of each new message by e-mail and in every app, which is why the e-mail address entered on the user’s extension record in the Admin Console matters: it is where the welcome e-mail and the voicemail notifications are delivered.

Step 5: Test Your Voicemail Setup

After configuration:

Call your extension from another number
Let the call ring until voicemail answers
Leave a test message
Verify playback and notifications

Testing ensures your voicemail setup works correctly before going live.

Expert Tip from ITS UAE

One of the most common mistakes during 3CX voicemail setup is incorrect call forwarding configuration. If forwarding rules are not set properly, voicemail may not activate even if the app is correctly configured.

A stable SIP trunk connection also plays a major role in voicemail reliability and inbound call routing. Businesses looking to optimize communication costs and improve call quality can explore the cheapest SIP trunk for 3CX solutions available in the UAE market.

How to Set Up Voicemail on 3CX App iPhone

If you are using iOS, the setup process is very similar.

To configure voicemail on iPhone:

Open the 3CX iPhone app
Tap the keypad
Dial 999
Enter your PIN
Access voicemail options
Record your greeting

The iPhone version supports:

Push notifications
Voicemail playback
Greeting management
Remote voicemail access

Many remote employees use the iPhone version of the 3CX app to manage business communication while traveling.

Voicemail setup on iPhone follows the same logic as Android with slight interface differences. On both platforms the extension is provisioned by scanning the QR code shown in the Web Client, and 3CX notes that push subscriptions last 14 days in V20 Update 10, so a phone that has been offline longer may need a fresh QR code before voicemail alerts resume.

How to Set Up Voicemail on 3CX App Android

Businesses searching for how to set up voicemail on 3CX app Android usually want a quick configuration process for remote teams.

To configure voicemail on Android:

Open the Android application
Access the dial pad
Dial the voicemail extension
Enter your voicemail PIN
Configure greetings and notifications

If you are learning how to install 3CX on Android phone devices, make sure:

Push notifications are enabled
Microphone permissions are granted
Battery optimization is disabled for the app

These settings help ensure voicemail notifications work properly; 3CX’s Android guide makes following its battery-optimisation instructions part of the initial setup, and its PUSH troubleshooting guide is the first stop when alerts stop arriving.

Android users may need to enable additional permissions for notifications and microphone access.

How to Change Voicemail on 3CX App

If you already have voicemail configured and want to update your greeting:

Open the 3CX mobile app
Dial voicemail
Enter your PIN
Press 9 for options
Press 8 to manage greetings

This process allows users to:

Change voicemail greeting
Update business hours greetings
Record temporary messages
Configure holiday greetings

Many companies update voicemail greetings during holidays, remote work schedules, or support outages.

How to Listen to Voicemail Messages in 3CX

Users can log into the web client dashboard and access voicemail directly from the sidebar menu.

The web client supports:

Message playback
Message deletion
Downloading voicemail audio
Voicemail forwarding

From the Windows Desktop App

If you are learning How to Setup 3CX on Windows client systems, voicemail access is built directly into the application interface.

Users can:

Listen to messages

From the iPhone or Android App

Inside the mobile app, users can:

Play voicemail messages
Delete messages
Call back contacts

3CX Voicemail Number and Menu Options

The 3CX voicemail system uses simple keypad navigation to manage messages and settings. 3CX’s own desk-phone voicemail guide gives the menu as: dial 999, enter your PIN and #, then * to play messages, 9 for options or # to exit; inside options, 1 changes your status, 3 dials a number, 4 deletes all read messages, 5 changes the self-identification message, 6 plays mailbox information, 7 changes the PIN, 8 changes the greeting and 9 repeats the prompts.

The most commonly used voicemail access number is 999 or 9999, depending on your PBX configuration.

Voicemail Menu Options:

Press * → Play messages
Press # → Exit the voicemail menu
Press 4 → Delete all read messages (inside the 9 options menu)
Press 7 → Change PIN (5 changes your self-identification message)

Common 3CX Voicemail Problems and Fixes

Many users experience minor configuration issues when setting up voicemail in 3CX, especially in cloud PBX environments.

Voicemail Not Working on 3CX App

Possible causes:

Incorrect forwarding rules
Disabled voicemail
App registration issues

Solution:

Verify extension settings
Check call forwarding configuration
Restart the application

Unable to Change Voicemail Greeting

Possible causes:

Incorrect PIN
Permission restrictions
Corrupted audio recording

Solution:

Re-record greeting
Update the mobile app

Forgot Your Voicemail PIN

This is a common issue for remote employees.

Not Receiving Voicemail Notifications

Check:

Push notification permissions
Email notification settings
Mobile data restrictions

Android battery optimization sometimes blocks voicemail alerts.

Does 3CX Support Voicemail Transcription?

Yes, 3CX supports voicemail transcription, but it depends on your licence: 3CX’s documentation states that voicemail transcription requires a PRO licence, with Grok, Google Speech or OpenAI as the engine (listed as “VoiceMail Transcription via Grok, Google or OpenAI” in the edition comparison), while full call transcription and the AI features belong to the AI Edition — the tier 3CX renamed from Enterprise on 23 April 2026, when Enterprise+ was retired.

Some users search for 3CX voicemail converter, but the correct business term is voicemail transcription.

Voicemail transcription converts voice messages into text, helping teams:

Read messages quickly
Improve response times
Search message history
Support remote workflows

This feature is especially useful for customer support teams and sales departments.

Best Practices for a Professional 3CX Voicemail Greeting

A professional greeting improves customer experience and business credibility.

Best practices include:

Keep the message short
Speak clearly
Mention your company name
Provide callback expectations
Include emergency alternatives if needed

Avoid:

Background noise
Long greetings
Unclear instructions
