The system works through Session Initiation Protocol (SIP) trunk providers, with Telnyx, Twilio, and Ozonetel named as launch partners. These providers handle the connection to the public switched telephone network, while OpenAI manages the audio processing and session logic.\n\nThe update includes HD Voice support for higher-fidelity audio and full bidirectional DTMF signaling. This allows agents to both send and receive keypad tones, enabling them to navigate interactive voice response (IVR) systems and phone menus. The feature complements existing WebRTC and WebSocket transports for GPT-Live.\n\nThe API is priced at $0.05 per minute, a rate that has been in place since GPT-Live-1 reached the API on September 10, 2026. Businesses must also account for carrier charges from their SIP provider, meaning the total cost of a call is the sum of OpenAI’s fee and the provider’s charges. OpenAI is not acting as a phone carrier but is integrating its intelligence layer with established telephony infrastructure.","keyPoints":["OpenAI launched GPT-Live outbound telephony API on November 4, 2026, for general availability.","The API costs $0.05 per minute and works via SIP providers like Telnyx, Twilio, and Ozonetel.","New features include HD Voice and bidirectional DTMF signaling to navigate phone menus."],"whyItMatters":"This enables AI agents to initiate real-world phone interactions, automating customer service and sales outreach. By integrating with existing SIP providers, it lowers the barrier for businesses to deploy voice AI without building telephony infrastructure.","category":{"slug":"agents","name":"Agents & Tools","url":"https://digestai.news/category/agents"},"entities":{"companies":["OpenAI","Telnyx","Twilio","Ozonetel"],"models":["GPT-Live","GPT-Live-1"],"people":["Diego Almada Lopez"]},"firstPublishedAt":"2026-11-04T15:56:00Z","updatedAt":"2026-11-04T15:56:00Z","sourceCount":1,"hasPrimarySource":false,"sources":[{"outlet":"cryptobriefing.com","title":"OpenAI launches GPT-Live outbound phone calls API at $0.05 per minute","url":"https://cryptobriefing.com/gpt-live-outbound-telephony-api-general-availability","publishedAt":"2026-11-04T15:56:00Z","type":"press","primary":false,"lead":true}],"sourceNotes":null,"discussions":[],"thread":{"title":"Anthropic and OpenAI Race Toward Next Generation Models","url":"https://digestai.news/thread/anthropic-may-have-a-new-toptier-model-in-the-works","storyCount":3},"cite":{"text":"Digest AI, \"OpenAI launches GPT-Live outbound phone calls API at $0.05 per minute\", 4 November 2026, https://digestai.news/story/openai-launches-gpt-live-outbound-phone-calls-api-at-0-05-per-minute","publisher":"Digest AI","title":"OpenAI launches GPT-Live outbound phone calls API at $0.05 per minute","datePublished":"2026-11-04T15:56:00Z","url":"https://digestai.news/story/openai-launches-gpt-live-outbound-phone-calls-api-at-0-05-per-minute"},"generatedBy":"Written by Digest AI's editorial model from the linked sources; the sources are the record.","license":"Headlines, digests and key points are written by Digest AI and may be quoted with a link to the story page.
