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**Plivo Voice API.** US outbound at $0.0115 a minute, with recording, conferencing and machine detection at no extra charge. 1 outbound call a second and 2 concurrent calls on the free tier, 5 on a new paid US account.\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### Plivo Voice API\n\n1. Point the answer URL at XML with a Stream element and bidirectional set to true for a live voice agent\n2. Check concurrency before dialling out in bulk. Above it calls are rejected with hangup cause 5030, above CPS they queue\n3. Don't rely on the status callback alone to learn a call ended. Poll the call if the webhook doesn't arrive\n4. Validate webhook signatures before acting on call events\n\n## Questions\n\n### Which is better for AI agents, LiveKit Telephony or Plivo Voice API?\n\nLiveKit Telephony scores 67.5 (B) on agent readiness against Plivo Voice API's 60.4 (C), and leads in 4 of 7 scored categories.\n\n### Do LiveKit Telephony and Plivo Voice API need an API key?\n\nBoth need an API key.\n\n### Can an agent call LiveKit Telephony and Plivo Voice API without installing anything?\n\nNo hosted endpoint is listed for LiveKit Telephony. Plivo Voice API has a hosted endpoint at https://api.plivo.com/v1.\n\n### Are LiveKit Telephony and Plivo Voice API 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 Plivo Voice API.\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/livekit-telephony-vs-plivo-voice.json, and with the fewest tokens: https://www.anchorterminal.com/compare/livekit-telephony-vs-plivo-voice.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"livekit-telephony\", \"b\": \"plivo-voice\"}`.
