Voicemails are nothing but static

[Gandalf the White]

We have had several cases where outside callers will leave a voicemail, but when we open the email attached MP3, there's no voice audio and just a bunch of static. The weird part is that the audio files are various lengths: 0:30, 2:41, 1:17, etc. so it's trying to record but not quite able to pull it off.

I ran a test by calling the main line from my cell phone and the VM sounds totally normal. Any idea why it wouldn't work with other callers?

Hi @Gandalf the White,

Can you provide information? https://www.3cx.com/community/threads/information-to-provide-when-requesting-help.67558/

Is this happening with internal calls as well or only external calls?

I updated the original post with more details.

Q: Is this happening with internal calls as well or only external calls?
A: Internal calls/VMs are fine: we don't generally leave each other VMs but it worked when I tested it.

Hi @Gandalf the White,

You mentioned an attached MP3 file, do you mean an attached WAV file?
