## What is OwnLine?

OwnLine is a bring-your-own-account dialer for developers. Connect your own Twilio or Telnyx account and get a full-featured softphone: voice calls, SMS conversations, and optional AI-powered live subtitles and interpretation via your own self-hosted AI server.

BYOA — your keys, your bill, your data:
• Paste your Twilio Account SID + Auth Token (or API key). OwnLine auto-provisions the TwiML app, serverless function, and API key in YOUR account.
• Or use a Telnyx API key — outbound voice profile, credential connection and SIP credential are set up automatically.
• Credentials are stored only in the device Keychain and never leave your device.

Features:
• Voice calls over Twilio or Telnyx WebRTC with CallKit integration
• Dual-provider SMS conversations
• DTMF keypad, mute, speaker
• Optional AI Call Assistant (requires your self-hosted OwnLine server plus your own OpenAI/Deepgram keys): live word-by-word subtitles, consecutive interpretation, AI-operated calls with human takeover
• Demo Mode — explore every screen without any account
• English and Simplified Chinese localization

OwnLine has no backend of its own: the app talks only to Twilio, Telnyx, and any AI server you configure yourself. No analytics. No ads.

Twilio and Telnyx are trademarks of their respective owners. OwnLine is an independent app and is not affiliated with or endorsed by them.
