## SMS Storage (SQLite with FTS5)

Messages are stored in a single SQLite database with full-text search.

### Storage

```
~/.dialpad/sms.db  # Single file with messages + FTS5 index
```

### Commands

```bash
# List all SMS conversations
python3 sms_sqlite.py list

# View specific conversation thread
python3 sms_sqlite.py thread "+14155551234"

# Full-text search across all messages
python3 sms_sqlite.py search "demo"

# Show unread message summary
python3 sms_sqlite.py unread

# Statistics
python3 sms_sqlite.py stats

# Mark messages as read
python3 sms_sqlite.py read "+14155551234"

# Migrate from legacy storage
python3 sms_sqlite.py migrate
```

### Features

- **Full-text search** via FTS5 (`search "keyword"`)
- **Fast queries** with indexes on contact, timestamp, direction
- **ACID transactions** — no corruption on concurrent writes
- **Unread tracking** with per-contact counts
- **Denormalized contact stats** for instant list views

### Webhook Integration

```python
from webhook_sqlite import handle_sms_webhook, format_notification, get_inbox_summary

# Store incoming message
result = handle_sms_webhook(dialpad_payload)
notification = format_notification(result)

# Get inbox summary
summary = get_inbox_summary()
```

### Legacy JSON Storage (Deprecated)

The original JSON-based storage is still available but not recommended:

```bash
python3 sms_storage.py [list|thread|search|unread]
```

## Requirements

- Python 3.7+
- No external dependencies (uses stdlib only)
- Valid `DIALPAD_API_KEY` environment variable
- For ElevenLabs TTS: `ELEVENLABS_API_KEY` + webhook setup for audio playback

## Reading SMS Messages

Dialpad doesn't provide a direct "GET /sms" endpoint. Instead, use:

### 1. Real-Time: SMS Webhooks

Receive SMS events in real-time when messages are sent/received.

```bash
# Create a webhook subscription
python3 create_sms_webhook.py create --url "https://your-server.com/webhook/dialpad" --direction "all"

# List existing subscriptions
python3 create_sms_webhook.py list
```

**Webhook Events:**
- `sms_sent` — Outgoing SMS
- `sms_received` — Incoming SMS

**Note:** Add `message_content_export` scope to receive message text in events.

### 2. Historical: Stats Export API

Export past SMS messages as CSV.

```bash
# Export all SMS
python3 export_sms.py --output all_sms.csv

# Export by date range
python3 export_sms.py --start-date 2026-01-01 --end-date 2026-01-31 --output jan_sms.csv

# Export for specific office
python3 export_sms.py --office-id 6194013244489728 --output office_sms.csv
```

**Output:** CSV file with columns:
- `date` — Timestamp
- `from_number` — Sender
- `to_number` — Recipient
- `text` — Message content
- `status` — Delivery status
