You're asking which country calls originate from when using LiveKit Phone Numbers, and how that compares to Telnyx.
LiveKit Phone Numbers are US-only (local or toll-free) and support inbound calling only. Calls handled via LiveKit Phone Numbers originate in the United States, and outbound calling is not supported with LiveKit Phone Numbers right now.
With a third-party SIP provider like Telnyx, outbound calls originate from the country associated with the phone number (or as configured via region pinning), and full outbound calling is supported.
