You may experience one or more of the following:

​

Caller symptoms

• Caller hears only a beep and no voicemail greeting
• Caller hears silence instead of the voicemail message
• Caller cannot leave a voicemail
• Caller leaves a voicemail, but the recording is empty or silent
• Call never reaches voicemail and ends unexpectedly

​

Admin / Agent symptoms

• Voicemail recording shows 0 seconds or no audio
• Voicemail recordings do not appear in Call History

​

How Voicemail Works

Inbound voicemail can be created in two ways: The caller reaches a Voicemail action inside your call flow. You can configure:

• playback greeting
• assigned agent or group mailbox
• email attachment preferences

If the call is routed directly to an unavailable agent (offline, busy, no device connected), their personal voicemail greeting plays and voicemail is stored in their mailbox.

​

Root Causes

​

⚠️ Call Flow configuration issues

• Missing Playback step before the Voicemail action
• Voicemail action placed in the wrong branch of the call flow
• Wrong agent or group selected as the voicemail recipient
• “Send voicemail to agent’s email” disabled
• Company-level voicemail settings override call flow
• The call never reaches the Voicemail action (misrouting)

​

⚠️ Agent voicemail issues

• Agent voicemail greeting not uploaded or corrupted
• Agent voicemail disabled
• Incorrect agent email
• Agent status rules prevent voicemail (for example, logged out in Phone app)

​

⚠️ Voicemail audio problems

• Caller hears only a single beep (no greeting played)
• Greeting file unsupported or damaged
• Caller hangs up too quickly
• Recording exceeds the 10-minute limit
• Connection instability during recording
• Audio device conflict in the CloudTalk Phone app

​

⚠️ Email delivery problems

• Email notifications disabled in the Voicemail action
• Email disabled at the account level
• Agent email incorrectly entered
• Email delivered to Spam/Junk
• Email provider blocking attachments

​

⚠️ Dashboard visibility issues

• Voicemail still processing
• Voicemail saved under a merged contact
• Ring group owner sees the voicemail but agent does not
• Agent lacks permission to view recordings
• Searching by name instead of phone number hides the entry

​

⚠️ CloudTalk Phone playback issues

• Outdated CloudTalk Desktop version
• Using an outdated operating system
• Wrong audio output device selected
• Connection issues affecting playback
• Browser permission problems (if using web app)

​

Step-by-Step Troubleshooting

1. Go to Numbers > Select the number > Basic settings.
2. Under Sequence of steps for incoming call, click Configure call flow.
3. In the Call Flow Designer, confirm that a Voicemail action is present.
4. Make sure the voicemail block sits on a path callers can actually reach (typically the Unanswered branch).
   
5. Open the Voicemail action (gear icon) and verify that the correct agent or group mailbox is selected.
6. If multiple Voicemail blocks exist, make sure the call reaches the intended one

If the caller hears silence or only a short beep, it usually means there is no Playback action before the Voicemail block. This is expected behaviour: without playback, CloudTalk plays only the “beep,” which many callers interpret as an error. To fix this:

1. In the call flow, add a Playback action before the voicemail.
2. Upload or record a short message (for example: “You have reached our voicemail. Please leave your message after the tone”)
3. Save and publish the call flow.

In the Call Flow Designer, locate the Voicemail block and click the gear icon inside the Voicemail block to open its configuration panel. Review the following options:

• Send voicemail to agent’s email
• Attach voicemail recording to the email

These can be set to:

• Yes
• No
• Use company settings

If “Use company settings” is selected:

1. Go to Settings > General > Basic settings.
2. Check global voicemail options for notifications and attachments.

If global email delivery is disabled, voicemail emails will not be sent even if your call flow tries to send them. Voicemail emails will not be delivered if:

• the email address contains a typo
• the user is deactivated
• the group email address is outdated
• the agent’s profile does not have an email at all

To check:

1. Go to Users or Groups (under Operations in the menu).
2. Open the assigned user or group.
3. Verify the email is correct and active.

If a voicemail exists in Call History, but the email notification never arrived:

• It may be filtered into Spam, Junk, Promotions, or Other Inbox tabs.

This is especially common with Outlook and Gmail. Open Dashboard > Call History and examine the call details. If voicemail is missing:

• The call may have been answered elsewhere in the flow.
• The ringing timeout might be too long.
• The call might be stuck ringing agents who appear “Available” but are not using CloudTalk Phone.
• The caller may have hung up before your Playback greeting finished.

If the call does not show “Voicemail” in its timeline, the issue is routing, not voicemail itself. If a voicemail appears, but audio is missing or silent:

• The caller may have hung up too early.
• There may have been network issues during the recording.
• The voicemail exceeded the 10-minute limit.
• The caller may have waited through silence because the Playback step was missing.

You can listen to the voicemail directly in Call History to confirm. If your flow routes directly to an agent and relies on agent voicemail, check:

1. Agent voicemail is enabled.
2. The agent has an active greeting.
3. The greeting file is valid (not corrupted).
4. The agent’s CloudTalk Phone app is connected and not stuck in an invalid status (for example, logged out or offline).

Agent voicemail behaves differently from call flow voicemail, so both need to be checked if you use mixed routing. If the voicemail exists but cannot be played in the CloudTalk Phone app:

• Check the audio output device in Settings > Microphone & Speakers
• Make sure the CloudTalk Phone Desktop app is up to date
• Avoid outdated operating systems (they may cause playback issues)
• If using the browser version, confirm microphone and audio permissions

This affects only playback, not voicemail creation. If the issue persists:

1. Create a new test flow.
2. Add only:
   • Playback
   • Voicemail
   • End call
3. Route a test phone number to this flow.
4. Test from an external number.

If the simple flow works, the issue is in the original routing logic. If the simple flow fails, this points to voicemail settings, file issues, or email delivery.
