How to turn voicemails into tasks with AI

Updated · by Rosh Perera

Voicemails pile up when you're on a job, and listening to them one by one at the end of the day is slow. Many phone systems already transcribe voicemail and email you the text. An AI agent can turn those transcripts into a clean task list: who called, their number, what they need, how urgent it is and a drafted callback text. You decide who to call first. Not sure which job fits your business first? Answer 5 quick questions in our free planner.

What to hand to an agent first

  • Get transcripts by email

    Turn on voicemail transcription in your phone or VoIP service and send the emails to an inbox the agent reads (for Grok Bot, its own email address works).

  • Pull out the task

    For each voicemail: caller name if given, number, what they want, any address or date, and whether they're new or existing.

  • Sort by urgency

    Tag each one urgent, today or this week, using your own words list. Anything urgent comes to you right away.

  • Draft a callback text

    A short reply for each that confirms you got the message and offers a time to call, for your OK.

  • End-of-day list

    At 17:00, one message with every voicemail still waiting, oldest first.

Copy-ready prompt

When a voicemail transcript email arrives from [phone service address]:
1. Pull out: caller name (or "unknown"), number, what they want, address or date mentioned, new or existing (check [customer sheet]).
2. Tag urgency: "urgent" if it mentions [urgent words]; "today" if they ask for a callback today; else "this week".
3. Draft a 2-line text: "Hi [name], got your message about [need]. I can call you at [time]. Does that work?"
4. If "urgent", post it here at the top with "CALL NOW".
At 17:00, post every voicemail not marked "done", oldest first.
Rules:
- If any field is unclear in the transcript, write "unclear". Never guess a number.
- Don't send texts. Post drafts here for my OK.

Works as a Grok Bot routine, a ChatGPT scheduled task or a Claude project instruction. Fill in the [brackets] first. It only writes drafts.

Example: Grok Bot setup

Grok Bot routine: Missed-call text-back that books the job
Schedule: Always on (missed calls)

When I miss a call, draft a short text to the caller: apologize, ask what they need, and offer two booking times from my calendar. Send me the draft to approve, and only send it to the caller after I approve it. (Instant sending is an optional upgrade once you trust the wording.) Log the lead and notify me with a summary.

Rules: draft first, never send or post anything external without my approval. Keep summaries short.

Setup steps

  1. Turn on voicemail transcription by email in your phone service.
  2. Forward those emails to an inbox your agent reads.
  3. Write your urgent words and your normal callback times.
  4. Paste the prompt below and run it on a week of old voicemails.
  5. Schedule the end-of-day list.

Keep these human

  • Transcripts can be wrong; check names, numbers and addresses before you act.
  • Emergency words (gas, flooding, no heat for vulnerable people, medical) ring your phone, not a list.
  • Voicemails can include personal details; keep the inbox private.
  • Start in draft mode: the agent prepares, you approve, then loosen the leash one routine at a time.

FAQ

Can AI transcribe voicemails?

Many phone systems already do and email you the text. The agent works from that transcript.

Can Grok Bot read my voicemails?

If your phone service emails transcripts, forward them to your Bot's email address or a connected inbox and it can turn them into tasks.

What if the transcript is wrong?

Check numbers and addresses before calling or visiting. The agent should write 'unclear' rather than guess.

Can it call people back?

Keep callbacks with you. The agent drafts a text you approve.
