Voicemail Tool
Turns an office phone system's voicemail into a searchable, AI-triaged inbox
Staff read voicemails instead of dialing in: every message is transcribed, summarized into a one-line caller intent, and ranked High / Medium / Low with AI so urgent calls get answered first. Tags, notes, forwarding and per-extension access included.
Voicemails start on the organization's own phone system, which is not exposed to the internet. A small bridge program on an office computer collects new messages and uploads the audio to cloud storage, then reports its own health — heartbeats, CPU and memory — to an admin panel so anyone can see at a glance that the pipeline is alive.
Each message is transcribed by a speech-to-text service that handles multiple languages, and an AI model condenses the transcript into a one-line caller intent plus an urgency — High, Medium or Low — with the reason spelled out. Staff can steer the triage in plain English: write "calls about missed deliveries are always High" in the settings and the AI follows it.
The inbox itself is a server-rendered TypeScript app on an SQL database with per-user access rules: each staff member sees only the extensions assigned to them, and shared lines can be visible to a whole team. Filters by urgency, date and tag, notes, forwarding and mark-as-read replace dialing into the voicemail box entirely. Accounts are created by an admin — there is no public sign-up.
What you get with a project like this
- Voicemails you read like email — with the audio one click away
- A transcript, a one-line caller intent and an urgency for every message
- Plain-English instructions to tune what counts as urgent
- Tags, notes, forwarding and read/unread — triage as a team
- Per-extension access: staff see only the lines assigned to them
- An admin panel with pipeline health and user management
- The phone system itself stays completely off the internet
