Rich, branded messaging in the native messages app.
RCS brings app-like cards, carousels and suggested replies to the default messages app. Your agent uses them for offers, bookings and confirmations — and falls back to SMS when a phone can't receive RCS.
- Rich cards, images, video, carousels and suggested replies.
- Link buttons, location pins and pay buttons.
- Automatic SMS fallback for phones without RCS.
- Same agent, memory and guardrails as voice and WhatsApp.
What customers see on RCS
- Rich cards and carousels
- Suggested replies and link buttons
- Images, video and documents
- Location pins and pay buttons
One agent writes once; each channel shows the reply in its best native format, and anything a channel can't draw becomes clear text and links — so no choice or link is ever lost.
The RCS problems Callaro solves
Plain SMS offers look like spam and convert poorly.
Branded rich cards, images and carousels make offers look like an app in the native inbox.
Not every phone supports RCS.
Messages fall back to SMS automatically, so no customer is missed.
Rich messages are one-way announcements.
Suggested replies and buttons go back to the agent, which answers and completes the task.
What the RCS agent does
Offers that look like an app
Product and plan carousels with images and buttons, right in the messages inbox.
One-tap actions
Suggested replies, booking times and pay buttons turn a message into a completed task.
Never lose a customer
If a phone can't receive RCS, the message goes out as SMS — automatically.
Shared context
Replies land on the same customer record as calls and chats, so the agent always knows the story.
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.
One customer, one memory — across channels
RCS is one mouth of the same agent. Every message lands on the same customer record as their calls, chats and emails, so the conversation simply continues.
Event → RCS offer
Your system posts an event (roaming started, plan expiring) and the customer gets a rich offer card.
RCS → call
A customer with questions taps to request a call at a time that suits them.
