Does it replace my existing voicemail box?

It can. Or it can supplement it — keep the existing box for compliance, and let Open's AI process the messages in parallel.

How accurate is the transcription?

Speech-to-text accuracy is in the 90%+ range on clear audio in supported languages. Accents and background noise are handled gracefully; ambiguous segments are flagged in the transcript.

Can it classify by my own intent taxonomy?

Yes — you define the intents that matter for your business. Open's AI classifies each voicemail against your taxonomy.

What languages are supported?

Over 100 languages, with transcription and intent classification tuned per language.

Can it call the customer back automatically?

Yes — for the intents you allow. Configure which classifications trigger an AI callback, and the AI will dial within 60 seconds with full context.

Where does the transcript end up?

In your CRM or helpdesk as a structured comment, in the Open inbox, optionally in Slack/email/SMS — wherever you route it.

01 — Overview

How is AI voicemail different from a transcript service?

A transcript service writes down what the caller said. AI voicemail does the next three things automatically: classifies the intent, decides what to do, and either calls them back as AI or pages a human with full context. The voicemail becomes a task, not just an audio file.

Traditional business voicemail is a known dead-letter box. Customers leave a message, the audio file goes into a queue, somebody on the team listens to a few of them later in the day, callback rates are bad, and the customer who genuinely had an urgent issue has already moved on. The mailbox itself is fine — the workflow around it is broken.

Open's AI voicemail rebuilds that workflow. When the caller leaves a message, the audio is streamed through speech-to-text in real time. By the time the caller has hung up, you have a transcript, a detected intent ("appointment cancellation," "payment dispute," "sales inquiry," whatever your taxonomy is), a sentiment score, and a suggested next action. The next action either fires automatically (AI callback within 60 seconds, ticket creation in your helpdesk, calendar block, payment link via SMS) or pages the right human with the transcript and intent already attached.

Per-number routing makes the workflow specific to the caller. A voicemail on the sales line gets a sales workflow; one on the support line gets a support workflow; one to a specific account manager gets routed to that person's Slack with the customer's history attached.

The voicemail is also still a voicemail. Audio file, transcript, intent, sentiment — all four are filed in the call record, available in the Open inbox, and pushed to your CRM/helpdesk as a structured task or comment. Your existing reporting still sees the call leg; Open adds the structured outcome on top.

Languages are handled the same way as live calls — over 100 languages, transcription quality tuned per language, intent classification trained per language. There's no "English voicemail tier".
