Number rental and SIP trunking prices aren't published.\n\n**Infobip Calls API + MCP.** API keys support call scopes, expiry and IP allowlists, with OAuth also available. US outbound calls cost about $0.067 a minute.\n\n## Before you call either\n\n### Bandwidth Voice API + MCP\n\n1. Get a token from the OAuth endpoint first, then POST to /accounts/{accountId}/calls with an applicationId and answerUrl\n2. Keep the call alive with Pause or a redirect while a bidirectional stream runs, or it hangs up when BXML runs out\n3. Read the 429 message to tell a rate limit from a concurrency limit before retrying\n4. Load the MCP server with BW_MCP_PROFILE=voice to keep the tool list short\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## Other comparisons with Bandwidth Voice API + MCP or Infobip Calls API + MCP\n\n- [Bandwidth Voice API + MCP vs Exotel Voice API + MCP](https://www.anchorterminal.com/compare/bandwidth-voice-vs-exotel-voice.md)\n- [Bandwidth Voice API + MCP vs Plivo Voice API](https://www.anchorterminal.com/compare/bandwidth-voice-vs-plivo-voice.md)\n- [Bandwidth Voice API + MCP vs SignalWire Voice API](https://www.anchorterminal.com/compare/bandwidth-voice-vs-signalwire-voice.md)\n- [Bandwidth Voice API + MCP vs Sinch Voice API + MCP](https://www.anchorterminal.com/compare/bandwidth-voice-vs-sinch-voice.md)\n- [Bandwidth Voice API + MCP vs Telnyx Voice API + MCP](https://www.anchorterminal.com/compare/bandwidth-voice-vs-telnyx-voice.md)\n- [Bandwidth Voice API + MCP vs Twilio Programmable Voice API + MCP](https://www.anchorterminal.com/compare/bandwidth-voice-vs-twilio-voice.md)\n- [Bandwidth Voice API + MCP vs Vonage Voice API + MCP](https://www.anchorterminal.com/compare/bandwidth-voice-vs-vonage-voice.md)\n- [Bandwidth Voice API + MCP vs Voximplant](https://www.anchorterminal.com/compare/bandwidth-voice-vs-voximplant.md)\n- [Exotel Voice API + MCP vs Infobip Calls API + MCP](https://www.anchorterminal.com/compare/exotel-voice-vs-infobip-calls.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 Telnyx Voice API + MCP](https://www.anchorterminal.com/compare/infobip-calls-vs-telnyx-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", "meta": { "attribution": "Anchor Terminal (https://www.anchorterminal.com)", "docs": "https://www.anchorterminal.com/docs/", "generatedAt": "2026-10-04", "license": "CC-BY-4.0", "method": "https://www.anchorterminal.com/benchmark/", "methodology": "0.3", "openapi": "https://www.anchorterminal.com/openapi.json", "preview": false, "run": "2026-10-01", "runLabel": "October 2026 research run" }, "page": { "breadcrumbs": [ { "name": "Home", "url": "https://www.anchorterminal.com/" }, { "name": "Compare", "url": "https://www.anchorterminal.com/compare/" }, { "name": "Bandwidth Voice API + MCP vs Infobip Calls API + MCP", "url": "" } ], "description": "Bandwidth Voice API + MCP has a score of 63.7 (B) against Infobip Calls API + MCP's 60.5 (C).
