Step 1: Write the script
Five elements every business voicemail should contain:
- Identification — your business name, in the first three seconds.
- Reason — short and honest ("we can't take your call right now").
- Action — what the caller should do (leave a message, email, visit URL).
- Expectation — concrete callback time (e.g. "within one business day").
- Alternative — for callers who don't want voicemail.

Step 2: Generate (or record) the audio
Two options:
- Use an AI generator (recommended). Paste your script into our voicemail generator, pick a voice and language, preview, and download a phone-system-ready MP3. Total time: 3–5 minutes.
- Record yourself. Quiet room, decent USB mic, audio editor (Audacity is free). Plan for 30–60 minutes including takes and edits.
In both cases, the export should be: mono, normalized, in the format your phone system requires (see audio format guide).
Step 3: Upload to your phone system
Pick your platform for the exact upload steps:
RingCentral
Auto receptionist, IVR menus, user voicemail.
Google Voice
Personal Google Voice and Workspace Voice.
Microsoft Teams
Auto attendants, call queues, user voicemail.
Zoom Phone
Auto receptionists, queues, user voicemail.
Nextiva
NextOS auto attendants and call flows.

MP3 vs WAV, sample rate, length limits.
Step 4: Test
- Call the line yourself from a different phone — ideally a mobile, since most callers will be on cellular.
- Listen for clarity, volume, and any cut-off at the start or end.
- Try leaving a message — confirm the recording works, the mailbox isn't full, and you receive the notification.
- If after-hours routing is configured, test outside business hours too.
Step 5: Maintain
- Update for holidays. Switch to the holiday version 2 business days before closure; switch back the morning you reopen.
- Update for vacations and absences. A clear OOO greeting beats an outdated default.
- Audit annually. Phone numbers change, hours shift, callback expectations evolve. A yearly review keeps things current.
