Why teams choose Callaro
Callaro is model-agnostic: choose the best STT, LLM and TTS for each agent (Deepgram, Gemini, ElevenLabs, Soniox and more), avoid single-vendor lock-in, and see the exact per-minute cost from $0.06/min — with self-serve onboarding and white-label. And the same Callaro agent runs voice, WhatsApp, web and app chat, SMS, RCS, email and an API channel with one memory per customer — so the journey continues off the phone.
What Callaro actually ships
Not a feature list — these are capabilities built into the product, the ones that decide whether an agent runs outcomes in production.
One agent on every channel — one memory per customer
Phone, web browser and in-app calls, WhatsApp, website and app chat, SMS, RCS, email and a headless API channel — all run by the same agent. A call sends the brochure on WhatsApp mid-sentence, a chat turns into a call that knows the chat, and every channel remembers what happened on the others.
Live context inside the conversation
Payments, CRM changes and order updates from your systems reach open chats and live calls within seconds — the agent can say "your payment just came through" while the customer is still on the line.
Rich, actionable chat — and your own UI if you want it
Comparison cards, bookable slots, carts and checkout, checklists, carousels and forms on chat and WhatsApp; SDKs for web, iOS, Android, React Native and Flutter with in-app calls and call invites that ring the app; or a headless API channel to render everything in your own design.
One inbox for your team
Every channel in one live inbox: take over any conversation, reply in the same thread, hand it back to the AI — with hand-off alerts and summaries.
Best-of-breed models, per agent — no lock-in
Pick the STT, LLM and TTS for each agent (Deepgram, Gemini, ElevenLabs, Soniox, Smallest AI, Sarvam and more) and see the exact cost component by component. No proprietary-model lock-in, no bundled black box.
Truly native in any language — not English-first
Per-language pronunciation & normalization packs (Arabic, Chinese zh/ja/ko, Spanish, Portuguese and per-language Indian packs) plus evidence-based runtime language switching and locale-aware number/script handling — so the agent sounds local in Riyadh, Mumbai, São Paulo or Shanghai, not just accented English.
In-call orchestration that actually decides
Fetch context with a pre-call API, call your HTTP APIs mid-conversation, map responses to variables with JMESPath, chain one tool's output into the next, and let the AI decide in real time which API or tool to call — not a rigid, pre-wired menu tree.
Connect any external MCP server
Register any MCP server (bearer / API-key auth, automatic tool discovery, per-agent tool allowlist) alongside your own HTTP tools — import from cURL or Postman, every tool call logged.
Transparent cost on every channel
Voice from $0.06/min with the exact per-minute stack shown before launch; chat and messaging billed by tokens, once per conversation, with daily spend caps — no seat licenses and no surprise analytics fees.
Bulk auto-dialer with timezone intelligence
Outbound campaigns with CSV audiences, timezone-aware scheduling, automatic retries and built-in DNC / do-not-call suppression — a real dialer, not a build-it-yourself loop.
Hybrid voicemail & answering-machine detection
Carrier AMD plus an in-call audio/transcript classifier, with AI-composed voicemail messages — hang up, leave a message, or keep going, configured per agent.
Real barge-in and call screening
Interruption handling with echo-storm detection so the agent knows real speech from its own echo — plus screening that tells a live person from a machine or IVR before it speaks.
Actions mid-call, grounded by your knowledge base
MCP and HTTP tool calls, CRM writebacks, bookings, payment links and ticket creation during the call — answered from a knowledge base (RAG), with every tool call logged.
Cross-call memory + configurable after-call analysis
Repeat callers pick up where they left off; define your own prompts to score, tag and extract from every stereo-recorded call — not just a canned sentiment score.
Bring your own telephony + full white-label
Connect your carrier (Twilio, Plivo, Exotel, Ozonetel and more) and your WhatsApp, SMS, RCS and email accounts, and resell under your own brand with partner → tenant → sub-account hierarchy, markup and billing.
