Voicemail Greetings

A voicemail greeting is the audio message callers hear when they reach a voicemail box. If no custom greeting is set, DialStack plays a default system announcement. Customizing the greeting lets you welcome callers in your own voice, set expectations about response time, or provide alternate contact options.

Where Greetings Live​

Greetings are managed on the detail page of the mailbox they belong to:

  • User voicemail — on a user's detail page, in the Voicemail card.
  • Shared voicemail boxes — on the box's detail page, in the Settings card.

Each mailbox has a single greeting slot (the "unavailable" greeting). Uploading a new greeting replaces the previous one.

Recording a Greeting​

  1. Open the user or shared voicemail box detail page.
  2. Locate the Unavailable Greeting control.
  3. Click Record, then Start recording.
  4. Speak your message. The timer shows elapsed time — keep it under 90 seconds.
  5. Click Stop when done.
  6. Review the recording with the inline player. Click Use recording to save, or Discard to try again.

Recording requires microphone access in your browser. Your browser will prompt for permission the first time.

Uploading a Greeting​

  1. Open the user or shared voicemail box detail page.
  2. Locate the Unavailable Greeting control.
  3. Click Upload, then drop an audio file onto the drop zone or click to browse.
  4. The file uploads and becomes the active greeting immediately.

Accepted formats: WAV, MP3, M4A, OGG, or WebM.

Limits: 5 MB maximum file size, 90 seconds maximum duration. Files are converted to telephony-quality audio server-side — the exact format you upload doesn't affect the final playback quality.

Replacing or Removing a Greeting​

  • Replace: upload or record a new greeting. It takes effect immediately.
  • Remove: click Remove next to the active greeting. The mailbox falls back to the system default announcement on the next call.

What Callers Hear​

When a call lands in the voicemail box:

  1. The greeting plays.
  2. A beep indicates recording has started.
  3. The caller leaves their message.

If the greeting file is missing or cannot be played for any reason, DialStack automatically falls back to the default system announcement so callers always hear something and can leave a message.

Tips​

  • Keep greetings short and clear. 15–30 seconds is usually enough.
  • State the name of the person or team being reached so the caller knows they dialed the right number.
  • Mention any alternate contacts or expected response time if relevant.
  • Record in a quiet room. Background noise is amplified over the phone network.
