AI voice agents that pick up, qualify and book
An AI agent answers your line in natural speech, follows your prompt, calls your functions, and hands to a human the moment it should.
A bot owns itself, and nothing else
The most useful decision in Convarza AI is a boundary: an AI bot knows its prompt, its voice and its functions — and knows nothing about where it is used. You point a channel, a call flow or a campaign at it. One bot, many places, one place to change it.
Prompt & first message
What it is for, how it should behave, and the exact line it opens with.
Voice per language
One agent, right accent. Set the voice for each language it is allowed to speak.
Functions
The things it may do mid-call — look something up, create a record, offer a slot.
Knowledge base
PDFs, documents and crawled pages, indexed. One KB can serve many bots.
Bots, bot flows, knowledge bases
Under one "AI bots" heading there are three things, because they have three different lifetimes.
- AI bots — the agent itself: prompt, opening line, voice, functions, model.
- AI bot flows — bots chained in order, each step carrying the handover condition that moves the conversation to the next one.
- Knowledge base — documents and crawled pages, indexed once, used by many bots.
Agents never see any of it. Managers and admins do — it is daily building work, not configuration, which is why it sits in the rail and not buried in settings.
One line answers with one thing
A channel points at an AI bot, or at a call flow. Never both, never neither — which is the only reason you can ever say for certain what picked up the phone.
Straight to the agent
The AI bot answers immediately. Good for an after-hours line, an overflow number, or a campaign that only needs to qualify.
Through a call flow
Steps decide: ring agents first, check business hours, run an IVR menu, then hand to the AI agent — or take voicemail. See call flows.
The graph is deliberately cyclic. A call flow can contain an AI call bot as a step; an AI call bot can hand back to a call flow; a flow can nest another flow. That is why every flow carries a Used-by list.
Bring your own carrier
Twilio
Point a Twilio number at Convarza and choose what answers it: your agents, an AI voice agent, or a call flow.
Maqsam
Connect your Maqsam account, set the region and direction, and route the line like any other.
SIP — outbound
Username, password, port, server, protocol and media encryption — with registration if your carrier wants it.
SIP — inbound gateway
Give the IP or domain of your gateway and the protocol. Incoming calls hit your flow or your AI agent.
Every calling channel gets Resource, Region, Direction and Additional settings — forwarded-from numbers, forward-to number, IP/domain match list, ping timeout and allowed concurrent calls.
AI voice agent FAQ
What can an AI voice agent actually do on a call?
It opens with your first message, follows the prompt you wrote, answers from a knowledge base you attached, calls the functions you gave it — look up an order, check availability, create a contact — and books into your calendar. When your guardrail says a human should take it, it hands over.
How good are the voices?
Voice quality is a plan tier. Starter uses the standard AI assistant, Pro adds human-like voices, Growth premium voices, Scaler ultra-realistic. Voice is set per language on the bot, so an agent can sound right in English and in Hindi without being two bots.
Which model does it run on?
You choose per bot — Claude, GPT, Gemini, or a low-latency hosted option when response time matters more than reasoning depth. The prompt, first message, functions and call timings all live on the bot alongside it.
Can the same bot answer chat and calls?
A bot is created as a chat bot or a call bot, because the two need different things — a call bot has timings and voices, a chat bot does not. Both are built in the same place and both know nothing about where they are used.
How do I stop a bot being deleted while something depends on it?
Every bot, flow and knowledge base shows a Used by list of the channels, campaigns and flows pointing at it. A referenced object is not silently deletable.
Does it work on my existing phone numbers?
Yes. Point a Twilio number, a Maqsam line, a SIP trunk or a SIP inbound gateway at Convarza and choose what answers it. The line keeps its own credentials, region, direction and calling hours.

Not a recording, not a menu, not a chatbot reading aloud. Here is what happens between the ring and the hang-up, and which parts you control.

The calls you miss between 7pm and 9am have a floor of zero, which makes them the safest place to start. The trick is knowing where to stop.

The line you connect decides your per-minute cost, your control over routing, and how bad a bad day gets. A plain comparison of the three.
