Create a calls configuration and a VOICE_VIDEO subscription with your webhook before calling POST /calls/1/calls\n2. Use your account's own base URL, not api.infobip.com\n3. Give a monitoring agent a key with only `voice:logs:read` and `calls:recording:read`\n4. For a quick spoken notification, the Voice MCP is simpler than the Calls API\n\n### jambonz\n\n1. Send `Authorization: Bearer \u003ctoken\u003e` to `https://api.jambonz.cloud/v1`, the server in the OpenAPI files. The REST introduction page gives `https://jambonz.cloud/api` instead, so confirm the base URL with the operator\n2. Create a call with `from`, `to` and either `application_sid` or `call_hook`. Do not retry a timed-out create without checking `GET /Accounts/{AccountSid}/Calls` first\n3. Read `ratelimit-remaining` and `ratelimit-reset` on every response and stop when a `429` arrives\n4. Append `#rc=3\u0026rp=5xx,ct` to an application URL to turn on webhook retries. HTTP webhooks are not retried by default\n5. Check the account has a carrier and speech credentials before dialling. jambonz does not supply numbers, minutes or speech services\n\n## Questions\n\n### Which is better for AI agents, Infobip Calls API + MCP or jambonz?\n\nInfobip Calls API + MCP scores 60.3 (C) on agent readiness against jambonz's 49.2 (D), and leads in 4 of 7 scored categories. jambonz leads on payments \u0026 pricing and maintenance \u0026 community.\n\n### Do Infobip Calls API + MCP and jambonz need an API key?\n\nInfobip Calls API + MCP takes an API key or an OAuth sign-in. jambonz needs an API key.\n\n### Can an agent call Infobip Calls API + MCP and jambonz without installing anything?\n\nInfobip Calls API + MCP has a hosted endpoint at https://api.infobip.com/calls/1. No hosted endpoint is listed for jambonz.\n\n### Are Infobip Calls API + MCP and jambonz open source?\n\nNo open-source release is listed for Infobip Calls API + MCP. jambonz is open source (Proprietary. jambonz.cloud is under the jambonz Terms of Use and self-hosted jambonz Commercial needs a paid licence key.
