Choosing an AI agent? Check these first.
Most AI voice demos sound great for ninety seconds. These are the twelve questions that decide whether an agent actually runs outcomes in production — and how Callaro answers each one.

The 12-point checklist
Run every AI voice agent — including Callaro — through these before you sign anything.
Can it handle your customers' real languages — including accents and code-switching?
Why it matters. Real callers switch languages mid-sentence and speak over noisy phone lines. An agent trained on clean English demos falls apart on the first live call.
Callaro. 77+ languages with native pronunciation and normalization packs — Arabic, Chinese, Spanish, Portuguese and per-language Indian packs — plus evidence-based mid-call language switching and code-switching, tuned for real telephonic audio, not studio recordings.
Can you choose and change the AI models behind each agent?
Why it matters. A single fixed model means you are stuck with its accuracy, latency, cost and language coverage. Needs change; your stack should too.
Callaro. Pick the STT, TTS and LLM for every agent, and swap any of them any time — no rebuild, no lock-in.
Is the cost transparent and controllable?
Why it matters. Bundled per-minute pricing hides where your money goes and makes cost-per-outcome impossible to manage.
Callaro. See the exact per-minute cost by component — STT, LLM, TTS and add-ons — before you launch. Calls start from $0.06/min, and you tune the stack to protect your margin.
Does it actually take action, or just talk?
Why it matters. An agent that only collects information leaves the real work — bookings, updates, payments — for a human to finish later.
Callaro. Tool calls mid-conversation: CRM writebacks, bookings, and payment or SMS links sent during the call, with results pushed to your systems.
Does it follow up and persist until the outcome lands?
Why it matters. One attempt rarely closes the loop. No-answers, busy tones and reschedules are where most outcomes are won or lost.
Callaro. Automated retries, reschedules that respect the customer's preferred time, and multi-touch cadences across a sequence of calls — every attempt logged.
Can it personalize with your variables and per-contact data?
Why it matters. Generic scripts sound like robocalls. Real conversations reference the customer's name, history and context.
Callaro. Static, pre-call and call-metadata variables plus per-contact fields, so every call is personalized to the person on the line.
Is it one agent across every channel?
Why it matters. Rebuilding the same agent for voice, WhatsApp and chat multiplies your work and fragments the customer experience.
Callaro. Voice runs in production today. WhatsApp, Chat and RCS are coming on the same agent configuration — one brain, shared context, same outcomes.
Does it sound natural with low latency?
Why it matters. Awkward pauses and robotic turn-taking make callers hang up before the agent gets to the point.
Callaro. Phone-grade turn-taking, interruption handling and noise handling for natural, low-latency conversations on real lines.
Does it stay on-script and safe?
Why it matters. An agent that improvises off-policy is a compliance and brand risk you cannot audit after the fact.
Callaro. Guardrails with allowed and disallowed topics, plus deterministic fallbacks that keep the agent inside policy on every call.
Can it hand off to a human with full context?
Why it matters. A cold transfer forces the customer to repeat everything and undoes the trust the agent just built.
Callaro. Warm transfer to a person with the full transcript and detected intent, so the human picks up exactly where the call left off.
Can you see and measure everything it does?
Why it matters. Without transcripts, sentiment and outcome data you can't tell what's working — or defend a call when it's questioned.
Callaro. Transcripts, recordings, sentiment, outcome tags, QA flags and a full action log for every call — observability built into the platform.
Does it fit your telephony and integrations?
Why it matters. An agent locked to one carrier or with no real API forces rip-and-replace instead of slotting into what you already run.
Callaro. Bring your own telephony — Twilio, Plivo, Exotel, Ozontel, Mcube or Knowlarity — and integrate over REST, Webhooks and WebSockets.
Legacy IVR and generic bots vs. Callaro
The difference between an agent that takes a message and one that finishes the job.
