Voice Agents 3.0

Voice Agents 3.0 routes every call to the most powerful available model and automatically falls back to close runner-ups if there's an outage — no configuration required.

Best in class transcription which modifies on-the-fly as more of the conversation provides context, yielding the most accurate transcription currently possible.

Watch active voice AI calls as they happen: live transcript, live tool events, live handoffs. When a call needs a human, take it over directly from the monitor. The handoff is smooth — the caller isn't put on hold or rung again — and the human-handled portion is automatically transcribed and appended to the full call record. Just click the button and introduce yourself!

Agents can now look up a calling contact's existing appointments and reschedule them on the spot. Rescheduling keeps the same calendar and team member, validates availability the same way new bookings do, and fires all the standard confirmations and calendar sync events.

Test any agent live in your browser — no phone call required. You'll see the transcript build in real time, watch which tools the agent uses (and what they return), and safely try out booking, field extraction, and conditional tools without real side effects. Plus don't burn credits on testing. Test as much as you need - no credits used when testing in the browser!

Partially a result of better transcription, but also a dedicated model now runs to handle field extraction tools, alleviating your main agent of that work, helping it to stay focused and providing you with more reliable information recording.

Agents can now hand a live call to another AI agent mid-conversation — instantly, without a phone transfer, and with the full conversation history carried over. This replaces the old pattern of phone-transferring between AI agents (which forced callers to re-explain themselves). Use it to route to focused agents: phone-numberless experts that exist purely to handle one area, like billing, scheduling, or a specific product line.

Instead of relying on automated machine detection (which is unreliable across carriers), v3 agents simply listen and recognize a voicemail the way a person would. It's more intuitive and tested better in practice.

Browse and preview voices before choosing one, with photos and short audio samples. Voices are organized into two collections: (high-performing voices from our xAI) and (voices designed by and unique to ). Filter by gender, collection, and language, including multi-language capable voices. No legacy voices will remain on the platform.

Every v3 call log now includes a tab — a chronological timeline of everything that happened on the call with timestamps: transcript turns, tool invocations, interruptions, handoffs, and human takeover moments.

You can migrate your account from the AI Voice Agents page. Once migrated, you'll see updated agent editor options, the new browser test interface, the Transfers & Handoffs tab, and all v3 features immediately. Accounts not yet migrated continue on the legacy platform with no disruption. All accounts will eventually be migrated over (~30 days).
