You're asking if IP + port + number alone are enough to set up an outbound trunk. Short answer: usually not — you can create a trunk with those, but you'll most likely need authentication and a few other fields. What you can do now • You can create a trunk with a name, the provider address (IP/hostname and port), destination country, and the

numbers

array (the phone numbers). Important considerations • Most SIP providers require authentication (

auth_username

/

auth_password

). Plan to provide those credentials. • LiveKit Cloud nodes do not have a static IP range, so IP-based allowlisting for provider-side authentication is unreliable. Use username/password authentication when possible. If you want, tell me: • Which SIP provider you're using and whether they support username/password or IP-based auth. • The fields you currently have (name, address, port, numbers) and whether you can get credentials. I can then give step-by-step settings to try or the exact trunk payload to use. Sources: SIP APIs | LiveKit docs | SIP outbound trunk | LiveKit docs
