LiveKit's own phone numbers are US only and inbound only, so outbound calls need a third-party SIP trunk, and no 429 or retry guidance was found.\n\n**Twilio Programmable Voice API + MCP.** Twilio APIs SLA at 99.95 per cent for every paying customer, with 10 per cent credits. US outbound at $0.014 a minute, plus $0.0044 for Media Streams or $0.07 for ConversationRelay.\n\n## Before you call either\n\n### LiveKit Telephony\n\n1. Ask the operator for a short-lived token with only the `sip.call` grant to dial or transfer. Trunk, dispatch rule and number changes need `sip.admin`\n2. Use a third-party outbound trunk for outbound calls. LiveKit Phone Numbers only receive calls\n3. Set `wait_until_answered` on `CreateSIPParticipant` and read the SIP status on `SipCallError` before retrying. Voicemail answers with 200 OK\n4. Send every request as a JSON POST to `/twirp/livekit.SIP/\u003cMethod\u003e` or `/twirp/livekit.PhoneNumberService/\u003cMethod\u003e` on the project's own host, with `{}` for an empty body\n5. A released number is billed for the whole month, and the free Build allowance is a hard cap after which requests fail\n\n### Twilio Programmable Voice API + MCP\n\n1. Use `\u003cConnect\u003e\u003cStream\u003e` for two-way audio. It blocks further TwiML until the websocket closes\n2. Use `\u003cConnect\u003e\u003cConversationRelay\u003e` when you only want to handle text, and set `interruptible` for barge-in\n3. Trial calls reach only verified numbers in your sign-up country\n4. Retry a 429 with backoff, but check the Calls list before retrying a create that timed out, since there's no idempotency key\n5. Validate `X-Twilio-Signature` on every webhook and websocket upgrade\n\n## Questions\n\n### Which is better for AI agents, LiveKit Telephony or Twilio Programmable Voice API + MCP?\n\nTwilio Programmable Voice API + MCP scores 80.4 (A) on agent readiness against LiveKit Telephony's 67.5 (B), and leads in 5 of 7 scored categories. LiveKit Telephony leads on maintenance \u0026 community.\n\n### Do LiveKit Telephony and Twilio Programmable Voice API + MCP need an API key?\n\nLiveKit Telephony needs an API key. Twilio Programmable Voice API + MCP takes an API key or an OAuth sign-in.\n\n### Can an agent call LiveKit Telephony and Twilio Programmable Voice API + MCP without installing anything?\n\nNo hosted endpoint is listed for LiveKit Telephony. Twilio Programmable Voice API + MCP has a hosted endpoint at https://api.twilio.com/2010-04-01.\n\n### Are LiveKit Telephony and Twilio Programmable Voice API + MCP open source?\n\nLiveKit Telephony is open source (Proprietary cloud service under LiveKit's Terms of Service. The SIP service (livekit/sip), the protocol definitions, the CLI and the server SDKs are Apache 2.0). No open-source release is listed for Twilio Programmable Voice API + MCP.\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/livekit-telephony-vs-twilio-voice.json, and with the fewest tokens: https://www.anchorterminal.com/compare/livekit-telephony-vs-twilio-voice.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"livekit-telephony\", \"b\": \"twilio-voice\"}`.
