What is CallUltra?

CallUltra is a workspace for teams that want AI voice agents to handle inbound and outbound phone conversations. Start with a clear calling goal, configure the agent's role, opening message, and instructions, then connect it to a real phone workflow. Each call leaves a record you can review before you expand to more contacts.

During a live call, the agent listens and responds in the same conversation. It can capture details, record outcomes, search approved knowledge, schedule a callback, or hand a caller to a person. Teams can test a voice in the browser, run a monitored Quick Call to check the actual phone audio, and use transcripts and recordings to improve the agent. A campaign then applies that tested conversation to a lead list with schedules and pacing controls.

AI voice workflows

AI during a live call

CallUltra uses Google Gemini Live for real-time voice conversations. The model receives caller audio and streams spoken responses back into the call while producing conversation transcripts.

Agent instructions, caller context, and available built-in actions guide each response. When a knowledge search or connected action is needed, the agent can request it during the conversation and use the result as context.

Make your first test call

    Select a voice and language, then save the agent.

  3. 3
    Run a browser test

    Use the voice playground to check the conversation and prompt.

  4. 4

Before launching a campaign

Only scale a campaign after a controlled handset test confirms that the full greeting and caller reply are audible. If the call is silent, use the troubleshooting guide and keep the call ID for support.
