Voicemail Attachment Not Playing in Gmail? Here's the Fix
If your office phone system or VoIP service forwards voicemails to your Gmail and they won't play, you've found the right page.
This is one of the most common complaints from teams using cloud phone systems. The audio player shows up in Gmail, you click play, and either nothing happens or you get an error. The fix is straightforward once you understand why it's happening.
Fix it in under two minutes
Gmail Audio Player adds inline playback for all telephony voicemail formats. First 10 plays free, no account required.
Why Your Voicemail Won't Play in Gmail
Your phone system sends voicemail as an audio file attached to an email. The format it uses — almost certainly WAV µ-law, WAV A-law, GSM 6.10, or AMR — is a telephony codec designed for phone networks. Chrome's audio player cannot decode these formats. When you click play, Gmail hands the file to Chrome's built-in audio engine, which fails because it doesn't understand the codec.
The audio file is not corrupted. Your Gmail is not broken. Your browser is working correctly. This is a codec incompatibility that has existed for years and will not be resolved by Google.
Which Formats Cause This Problem
| Format | Used By | Gmail Can Play? |
|---|---|---|
| WAV µ-law | Most North American VoIP | No |
| WAV A-law | European & Australian phone systems | No |
| GSM 6.10 | Older PBX systems, some VoIP | No |
| AMR | Mobile voicemail, some VoIP | No |
| MP3 | Some modern platforms | Yes |
| Standard WAV (PCM) | Some systems | Sometimes |
If your voicemail has a .wav extension and still won't play, it is almost certainly encoded as µ-law, A-law, or GSM — not standard PCM audio.
The Quickest Fix: Gmail Audio Player
The fastest way to resolve this without changing your workflow is to install the Gmail Audio Player Chrome extension. It decodes telephony formats directly in your browser and adds an inline player inside Gmail.
After installing, voicemail attachments that previously showed a broken player will display a working audio player with play, pause, scrub, volume, and speed controls — all without leaving Gmail or downloading any files.
Install Gmail Audio Player →Free trial included
First 10 voicemail plays at no cost, no account required. Basic $9.99/month for unlimited playback. Pro $15/month adds AI transcription and summaries.
Other Options
Download and open in VLC
VLC Media Player is free and plays every telephony format. Download the attachment, open in VLC, listen. Works reliably but means leaving Gmail and managing downloaded files.
Use your provider's web portal
Most VoIP platforms have a web interface where voicemails play natively. This works but splits your communication management across two places.
Forward to a different email client
Outlook and Apple Mail sometimes handle these formats better. Unreliable and adds workflow complexity.
For Teams and Organisations
If multiple staff members have this problem — common in medical practices, legal offices, real estate agencies, and any team that runs voicemail-heavy workflows — Gmail Audio Player supports team deployments. Staff activate using their company email, no individual payment required per person.
Pro and Business plans include AI transcription powered by OpenAI Whisper so voicemails can be read as text inside Gmail, and AI summaries that extract the key information and next action from each message automatically.
