No per-number or per-minute price is public, API keys carry no scopes, orders have no idempotency key, and outbound calling needs an approved application. Calls travel over SIP only.\n\n**LiveKit Telephony.** Signed tokens separate the right to dial (`sip.call`) from the right to manage trunks (`sip.admin`), and per-minute prices are public with a free plan that needs no card. 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## Before you call either\n\n### DIDWW Voice and Number Management API\n\n1. Send `Api-Key: \u003ckey\u003e` with no `Bearer` prefix, plus `Accept: application/vnd.api+json`, and `Content-Type: application/vnd.api+json` on every request with a body\n2. Set `X-DIDWW-API-Version: 2026-04-16` on each request and read `meta.api_version` in the reply. A header older than the account's version is ignored\n3. Before retrying a timed-out `POST /orders`, list `GET /orders` first. The order is charged to the balance at once and no idempotency key exists\n4. Stay under 20 requests a second per key. On `429` wait before retrying, since no `Retry-After` header is documented\n5. Use `fields[...]`, `filter[...]`, `include` and `page[size]` (default 50, maximum 100) to keep JSON:API replies small\n6. Check `GET /address_requirements` before buying a number. Many countries need a verified identity and address, and the sandbox cannot run identity verification\n7. Create and enable a callback secret in the User Panel before relying on callbacks. Without one nothing is sent, and receivers must verify `X-DIDWW-Signature`\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## Questions\n\n### Which is better for AI agents, DIDWW Voice and Number Management API or LiveKit Telephony?\n\nLiveKit Telephony scores 67.5 (B) on agent readiness against DIDWW Voice and Number Management API's 65.1 (B), and leads in 4 of 7 scored categories. DIDWW Voice and Number Management API leads on agent ergonomics.\n\n### Do DIDWW Voice and Number Management API and LiveKit Telephony need an API key?\n\nBoth need an API key.\n\n### Can an agent call DIDWW Voice and Number Management API and LiveKit Telephony without installing anything?\n\nDIDWW Voice and Number Management API has a hosted endpoint at https://api.didww.com/mcp. No hosted endpoint is listed for LiveKit Telephony.\n\n### Are DIDWW Voice and Number Management API and LiveKit Telephony open source?\n\nNo open-source release is listed for DIDWW Voice and Number Management API. LiveKit 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).\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/didww-voice-and-number-management-vs-livekit-telephony.json, and with the fewest tokens: https://www.anchorterminal.com/compare/didww-voice-and-number-management-vs-livekit-telephony.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"didww-voice-and-number-management\", \"b\": \"livekit-telephony\"}`.
