Agent Studio

Build, test and run voice agents on your jambonz account, without writing a jambonz application.

Agent Studio is where you build a voice agent, call it from your browser, publish it to a phone number, and see every call it takes. It connects to your jambonz account (jambonz.cloud or your own jambonz) with an API key, and uses the carriers, phone numbers and speech and LLM credentials you already have there.

Four kinds of agent

You choose the kind when you create an agent. It decides where the agent’s thinking happens; everything else (phone numbers, transfers, tools, recording, call history) works the same for all four.

KindWhat it isChoose it when
Cascaded voice pipelinejambonz runs speech recognition, a language model and a voice that you chooseyou want control over each part: any LLM, the widest choice of voices, latency you can tune per stage
Realtime voice APIone vendor runs the whole voice loop: OpenAI Realtime, OpenAI GPT-Live, Deepgram Voice Agent, Rime Prism or Ultravoxyou want the lowest latency and the most natural turn-taking, with one vendor to configure
Connected agentan agent built on another platform, Dialogflow CES or ElevenLabs Agents, put on the phone by Studiothe agent already exists there, or your team builds agents there
Custom harnessyour own code decides what to say; jambonz listens, takes turns and speaksthe conversation logic is yours to own: your own models, retrieval, routing and checks. See Custom harness

What every agent gets

  • Phone numbers: route your jambonz numbers to an agent, for inbound calls, or place outbound calls from it.
  • Transfers and hangup: hand the caller to a person or another system (blind or warm, with a spoken brief), take them through a secure detour (for example, a payment) and back, and end calls cleanly.
  • Tools: HTTP tools and MCP servers the agent can call during a conversation.
  • Testing: call the agent from your browser or your phone and watch each turn as it happens.
  • Versions: publish a draft when it is ready; roll back to an earlier version at any time.
  • Call history: recordings, transcripts and each turn’s timing and tool calls for every call.
