Step-by-step upload guide

  1. Generate your greeting at phonegreetings.ai and download the WAV (Nextiva preset).
  2. Sign in to NextOS at nextos.nextiva.com.
  3. For an auto attendant: navigate to Voice → Auto Attendants → [auto attendant name] → Audio Files. For a call flow: Voice → Call Flows → [flow name] → Audio.
  4. Click Upload Audio and select your WAV.
  5. Give the file a recognizable name (e.g. "Main Greeting Q1 2026") and save.
  6. Assign the uploaded audio to the relevant prompt — Welcome, After Hours, Holiday, etc.
  7. Click Save on the auto attendant or call flow to apply the change.
  8. Test by calling the assigned number.

Common errors and fixes

  • "File format not recognized"
    NextOS rejects WAV files that aren't 8 kHz 8-bit mono μ-law. Re-export with the "Nextiva preset" in our generator, or convert manually using the format spec above.
  • Greeting sounds robotic / muffled
    Confirm the file is 8 kHz μ-law mono — not 16 kHz PCM. NextOS resamples PCM files less cleanly than μ-law.
  • "Audio file too large"
    Limit is 5 MB. Most voicemail greetings should be 15–25 seconds; trim if needed.
  • Holiday greeting doesn't play
    Holiday audio in NextOS requires a Holiday Schedule attached to the auto attendant. Upload the file first, then assign the schedule under the auto attendant's settings.

Frequently asked questions
