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

# 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

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:

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.

# Create a webhook subscription
python3 create_sms_webhook.py create --url "" --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.

# 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
