Carrier
Owns the phone account, lines, routing, and connectivity charges.
BYO telephony
Keep the line. Normalize the media.
Every carrier has a different stream envelope and playback-flush command. Your bridge translates that carrier dialect; your trusted server creates the project-scoped Dvaarik voice session.
The machine handoff is published and requires a project key on a trusted server. These guides document customer-owned carrier plumbing; they do not sell a line, imply provider endorsement, or authorize putting that key in browser code.
Reference registry dated 13 September 2026. Protocol references are official starting points, not proof that an account is enabled. Confirm the current carrier contract and account capabilities before implementation.
