One agent, every channel, one memory per customer.
Phone, in-app voice, website and app chat, WhatsApp, SMS, RCS, email and your own app — all live, all run by the same agent. Customers move between channels without starting over.
What you get
- Write the agent once — instructions, knowledge, tools and guardrails — and it adapts its style to every channel.
- One memory per customer: a WhatsApp reply knows what was agreed on yesterday's call.
- Cross-channel actions: send a brochure on WhatsApp mid-call, turn a chat into a call, follow up on the channel the customer chose.
- Live awareness: payments, CRM changes and order updates reach open conversations — even a live call — within seconds.
- Rich replies everywhere: buttons, catalogs, comparisons, booking slots, carts and checkout, shown natively or as clear text and links.
- One inbox for every channel: your team takes over any conversation, replies, and hands it back to the AI.
- Consent, opt-outs, quiet hours and do-not-contact respected on every channel.
- Outcomes, transcripts and collected data land in your CRM by webhook, whatever the channel.
→ Every journey ends in an outcome — a booked visit, a paid invoice, a resolved ticket — no matter how many channels it crossed.
The problems a single-channel bot can't solve
Customers don't stay on one channel, and neither do their journeys. These are the gaps Callaro was built to close.
Every channel runs on a different bot or tool, so customers repeat themselves each time they switch.
One agent and one memory per customer: a WhatsApp reply knows yesterday's call, and a call started from chat knows the chat.
Promises made on a call ("I'll send you the brochure") depend on someone remembering later.
The voice agent sends the brochure, location or pay link on WhatsApp, SMS or email while the customer is still on the line.
Payments, CRM updates and order changes don't reach the conversation happening right now.
Your systems post an event and every open conversation — including a live call — knows within seconds.
Customers who want to talk are stuck in chat; customers who want to text are stuck on hold.
Chats turn into calls in one tap, calls send messages mid-conversation, and follow-ups go out on the channel the customer chose.
Your team juggles separate inboxes and loses context on hand-off.
One inbox for every channel; a teammate takes over with a summary and hands it back to the AI.
Messaging automation risks spam complaints, opt-out violations and runaway costs.
Consent, quiet hours, abuse protection, per-conversation billing and daily spend caps apply on every channel.
How one agent serves every channel
Each channel is a different mouth for the same brain. The agent decides what to do; Callaro makes sure it is allowed, sends it the right way for the channel, and records it against the right customer.
One agent definition
Instructions, knowledge, tools and guardrails are written once. Each channel only changes the style: short spoken sentences on a call, buttons on WhatsApp, one concise message on SMS, a subject line on email.
Your channel accounts
Your phone numbers, WhatsApp number, SMS sender, RCS agent and email domain stay yours. Callaro applies each channel's rules for you.
One customer record
Every message and call is tied to the right customer — by phone number, authenticated email, a one-time code or your app's sign-in.
Conversations with outcomes
A chat starts, may pass to a person and back, and ends like a call: data collected, webhooks sent, follow-ups scheduled, memory updated.
Live context
Events from your systems and from other channels reach every open conversation with that customer — calls hear about them while they happen.
Actions as tools
The agent decides when to message on another channel, call back, schedule a follow-up, take a payment or bring in a person — within your consent and timing rules.
Cross-channel capabilities
Send during a call
The voice agent sends a WhatsApp, SMS, RCS or email — brochure, location, pay link — while the customer is still talking.
Send from a chat
A chat agent sends to the customer's WhatsApp, SMS or email when they ask for it.
Call me now
A customer asks to talk and gets a call right away — one that already knows the chat.
Ring the app
Your team, your system or the AI rings the customer's app; accepting starts an in-app voice call.
Follow-up on any channel
A call, WhatsApp, SMS or email at the time the customer asked for — retried if needed, within quiet hours.
Live events
Payments, CRM changes and order updates reach every open conversation within seconds — including a live call.
After the call
Open chats get a short summary of the call, and an optional recap email lists what was sent.
Hand-off to a person
Your team is notified with a summary, replies in the same thread, and hands back to the AI.
Tools, data and live events — inside the conversation, not after it
Most bots answer from a script and update your systems later. Callaro exchanges data with your systems while the customer is still talking — so nothing breaks when a journey crosses channels or something changes in real time.
Context in before the first word
Customer profile, CRM stage, open orders and the last conversation on any channel are loaded as the call or chat starts — the agent opens warm, never cold.
In-call tool calling
The agent calls your APIs, MCP servers and payment gateway mid-sentence — look up, book, update, charge — and uses the answer immediately.
Runtime context insertion
A payment, a CRM change or a chat message arrives while the call is live? It's inserted into the conversation within seconds, and the agent can say it aloud.
No broken hand-overs
Call to WhatsApp, chat to call, AI to human and back — each step carries the context forward, so customers never repeat themselves.
Engineered for speed
The agent is prepared before the call connects so the greeting is ready on the first moment of audio; prompts are cached, models chosen per use case, and turn-taking tuned for real phone lines.
- Hi, I'm calling about the 2BHK at Skyline Heights.
- Before the first word: CRM profile, last WhatsApp chat and open deal stage loaded into the agent's context.
- Welcome back, Priya — you asked about the east-facing units on WhatsApp yesterday. Two are still open.
- Tool call → inventory API: 2 units, live prices returned and used in the answer.
- Tool call → send WhatsApp: brochure, price sheet and site location delivered mid-call.
- Live event from your payment gateway: booking amount received.
- I can see your booking amount just came through — Unit 1204 is now reserved for you.
After the call: transcript, collected data and outcome to your CRM by webhook; open chats get a summary; a recap email lists what was sent.
Rich, actionable replies on every channel
The agent chooses the best format for each answer — and customers compare, book, pay and apply without leaving the conversation. Where a channel can draw it, they see it natively; elsewhere it becomes clear text and links.

Graceful everywhere
Where a channel can't draw a format, it becomes clear text and links — SMS gets numbered choices, email gets a table — so no choice or link is lost.
Chat and call, inside your own app
Drop Callaro into your website and mobile apps. The same SDK gives your users rich chat and in-app voice calls — and lets your team, your systems or the AI ring the app instead of the phone.
- Rich chat with cards, slots, carts, forms and file upload — styled to your brand.
- Tap to talk: an in-app voice call that already knows the chat and the signed-in user.
- Ring the app: send a call invite that rings the user's app — accept to start a voice call; missed invites are recorded.
- Signed-in users recognised with your own token — no second verification.
- Push notifications so invites and replies reach users when the app is in the background.

Omnichannel FAQ
Which channels does Callaro support?
Phone calls (inbound, outbound and campaigns), in-app and website voice, website and in-app chat (widget and SDKs for web, iOS, Android, React Native and Flutter), WhatsApp, SMS, RCS, email, and an API channel for your own interface. All are live.
Do I need to build a separate agent for each channel?
No. You define one agent — instructions, knowledge, tools and guardrails — and it adapts its style and formatting to each channel automatically.
Will the agent remember a customer across channels?
Yes. Each customer has one memory shared by every channel, so a WhatsApp reply knows what was agreed on a call and a call started from chat already knows the chat.
Can my team take over a conversation?
Yes. One inbox shows every channel. A teammate can take over, reply in the same thread and hand it back to the AI, which resumes from the last unanswered message.
How are consent and opt-outs handled across channels?
Opt-outs and do-not-contact requests are recorded per purpose and respected on every channel they apply to. STOP/HELP keywords are handled before the AI runs, and business-initiated messages follow quiet hours by market.
