US outbound calls cost about $0.067 a minute.\n\n**Telnyx Voice API + MCP.** About $0.007 a minute all-in for US outbound ($0.002 Voice API plus $0.005 termination). x402 and MPP only top up credit, they don't pay per call.\n\n## Before you call either\n\n### Infobip Calls API + MCP\n\n1. 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### Telnyx Voice API + MCP\n\n1. Create a Call Control application first. `POST /v2/calls` needs its `connection_id`\n2. Fund a new account through /v2/x402/credit_account or MPP before buying a number, since it starts at zero\n3. Only one media stream or fork runs per call, and starting a fork replaces the websocket stream\n4. Add the Voice API fee and SIP trunking rate together when pricing a call\n5. Set a unique command_id on every call command, so a retry after a timeout is ignored rather than repeated\n\n## Other comparisons with Infobip Calls API + MCP or Telnyx Voice API + MCP\n\n- [Bandwidth Voice API + MCP vs Infobip Calls API + MCP](https://www.anchorterminal.com/compare/bandwidth-voice-vs-infobip-calls.md)\n- [Bandwidth Voice API + MCP vs Telnyx Voice API + MCP](https://www.anchorterminal.com/compare/bandwidth-voice-vs-telnyx-voice.md)\n- [Exotel Voice API + MCP vs Infobip Calls API + MCP](https://www.anchorterminal.com/compare/exotel-voice-vs-infobip-calls.md)\n- [Exotel Voice API + MCP vs Telnyx Voice API + MCP](https://www.anchorterminal.com/compare/exotel-voice-vs-telnyx-voice.md)\n- [Infobip Calls API + MCP vs Plivo Voice API](https://www.anchorterminal.com/compare/infobip-calls-vs-plivo-voice.md)\n- [Infobip Calls API + MCP vs SignalWire Voice API](https://www.anchorterminal.com/compare/infobip-calls-vs-signalwire-voice.md)\n- [Infobip Calls API + MCP vs Sinch Voice API + MCP](https://www.anchorterminal.com/compare/infobip-calls-vs-sinch-voice.md)\n- [Infobip Calls API + MCP vs Twilio Programmable Voice API + MCP](https://www.anchorterminal.com/compare/infobip-calls-vs-twilio-voice.md)\n- [Infobip Calls API + MCP vs Vonage Voice API + MCP](https://www.anchorterminal.com/compare/infobip-calls-vs-vonage-voice.md)\n- [Infobip Calls API + MCP vs Voximplant](https://www.anchorterminal.com/compare/infobip-calls-vs-voximplant.md)\n- [Plivo Voice API vs Telnyx Voice API + MCP](https://www.anchorterminal.com/compare/plivo-voice-vs-telnyx-voice.md)\n- [SignalWire Voice API vs Telnyx Voice API + MCP](https://www.anchorterminal.com/compare/signalwire-voice-vs-telnyx-voice.md)\n- [Sinch Voice API + MCP vs Telnyx Voice API + MCP](https://www.anchorterminal.com/compare/sinch-voice-vs-telnyx-voice.md)\n- [Telnyx Voice API + MCP vs Twilio Programmable Voice API + MCP](https://www.anchorterminal.com/compare/telnyx-voice-vs-twilio-voice.md)\n- [Telnyx Voice API + MCP vs Vonage Voice API + MCP](https://www.anchorterminal.com/compare/telnyx-voice-vs-vonage-voice.md)\n- [Telnyx Voice API + MCP vs Voximplant](https://www.anchorterminal.com/compare/telnyx-voice-vs-voximplant.md)\n",
