# Tutorial: Setting Up Call Transcription on Cloud PBX (3CX)

This article covers the technical steps for enabling **Call Transcription** on a 3CX-based Cloud PBX system — from licensing requirements, choosing an AI engine, to configuring it per department/queue.

## **Prerequisites**

Before starting the configuration, make sure the following are in place:

- **3CX Enterprise license** — call recording transcription is only available on the Enterprise license. The PRO license only supports voicemail transcription.
- **3CX Admin Console access** with full (Super Admin) privileges.
- **Call Recording already enabled** on the extension, queue, or DID you want transcribed, since transcription works on top of the recording output.
- One of the following three AI engines, depending on your needs:
  1. **3CX AI** (native, convenient, no third-party account needed)
  2. **OpenAI Whisper / GPT Transcribe**
  3. **Google Cloud Speech-to-Text API**

## **Option 1: Using 3CX AI (Native)**

This is the fastest option since it doesn't require an external API account.

1. Go to **Admin Console > Integrations > Transcription**.
2. Select the **3CX AI** engine.
3. Enable **Stereo Mode** — this mode separates the caller's and callee's audio into distinct channels, making *speaker diarization* (identifying who's speaking) more accurate.
4. Select the transcription language from the **Speech Language** dropdown (e.g. Indonesian, English).
5. Click **Save**.

## **Option 2: Using OpenAI (Whisper / GPT Transcribe)**

1. Create an account at [platform.openai.com](https://platform.openai.com/) if you don't have one yet.
2. Create a new **Project**, then go to **Settings > Billing** to enable a paid plan.
3. Go to **Settings > Limits** and configure:
   - A **Monthly Budget** and **Notification Threshold**
   - Add the required models: whisper-1, gpt-4o-mini-transcribe, gpt-4o-transcribe
   - Set **Rate Limits** according to your call traffic capacity
4. Create an **API Key** for that project, then copy it.
5. Go back to **3CX Admin Console > Integrations > Transcription**.
6. Select the **OpenAI** engine and paste in the API Key you just created.
7. Select the transcription language, then click **Save**.

**Cost note:** If your 3CX license is 8SC or above, voicemail transcription via 3CX AI is usually free, but call recording transcription via OpenAI is still billed according to OpenAI's API usage.

## **Option 3: Using Google Cloud Speech-to-Text**

A good fit for companies already using the Google Cloud ecosystem.

1. Log in to the **Google Cloud Console** and create or select a project.
2. Enable the **Cloud Speech-to-Text API V2** for that project.
3. Configure **Google Cloud Storage** as the recording storage bucket:
   - In the 3CX Admin Console, open **System > Storage**
   - Enable **Enable Remote Data Storage & Archiving**
   - Select **Google Storage** as the location
4. Connect your Google account to 3CX via **Google Integration** and grant access (this requires a **Super Admin** role on that Google account/IAM project — the most common cause of failed integrations).
5. Go back to **Integrations > Transcription**, and select the **Google Speech** engine.
6. Select the **Speech Language**, then click **Save**.

**Important:** Call recordings get fully transcribed during the *remote archiving* process (immediately or on a schedule), not in real time as the call is happening.

## **Enabling Transcription per Department, Extension, Queue, and Ring Group**

Once the engine is configured, transcription doesn't automatically run for every user. You need to enable it at the appropriate level:

1. Go to **Admin Console > Departments**.
2. Select the department you want to enable transcription for.
3. Open the **Options** tab and set your transcription preference (Voicemail, Recording, or both).
4. Click **Save**.

By default, every user, ring group, and queue within that department will **follow the department-level setting**. If you need an exception for a specific extension, the setting can be overridden directly on that extension's page.

## **Viewing Transcription Results**

Once enabled, transcription results can be accessed in several places:

| **Platform** | **How to Access** |
| --- | --- |
| **3CX Web Client** | Open the Voicemail/Recordings menu; the transcript text appears next to the audio file |
| **Email** | If email notifications are enabled in the user's settings, the transcript is sent automatically for every recorded call |
| **Windows Softphone** | A transcript snippet appears in the call list; click the transcript icon for the full text |
| **iOS / Android App** | A transcript snippet appears in the call list; tap the transcript icon to open the full text |

## **Common Troubleshooting**

**1. Transcription doesn't appear for a certain user**

- Check whether the Department/Extension-level setting has actually enabled transcription.
- Make sure Call Recording is active for that user/queue — without a recording, there's nothing to transcribe.

**2. The Google Speech integration shows an error status (red outline)**

- Usually caused by the Google account used not having a **Super Admin** role in the IAM project.
- Make sure Google Cloud Storage is already configured as Remote Storage before connecting the Speech API.

**3. OpenAI transcription suddenly stops**

- Check the **Usage Limits** and **Monthly Budget** on your OpenAI account — transcription stops once your API quota/budget runs out.
- Make sure the API Key is still valid and hasn't been revoked.

**4. Speaker diarization results are inaccurate**

- Enable **Stereo Mode** in the transcription settings, since it separates caller and callee audio into distinct channels for more precise speaker identification.

**Recommendation for Enterprise Scale**

For companies with high call volume and strict data privacy requirements, transcription can be run locally (on-premise) via the **3CX Transcription Engine Server**, so voice data never has to be sent to a third party. This local deployment is recommended to run on a machine with a **high-performance GPU** to keep processing speed up.
