How it works

From zero to first AI call in under a day

Whether you're replacing a 20-seat call center or just your IVR greeting, setup follows the same path.

01

Port or buy a number

Bring your existing number via Twilio/Exotel, or rent a new DID from any region — inbound and outbound work the same day.

02

Design the conversation

Write a system prompt. Define tone, business hours, escalation rules. No dialogflow trees, no DTMF menus.

03

Connect your systems

Hook in your CRM, knowledge base, payment gateway, or appointment system via tools and webhooks. The agent reads and writes.

04

Route calls + go live

Forward inbound to the AI agent, or kick off outbound call campaigns from the dashboard. Live transcripts stream in real time.

Features

What makes CallMissed voice agents actually usable in production

The hard parts of voice AI — latency, barge-in, language handoff, tool calls — all handled.

Barge-in + natural turn-taking

Customers can interrupt the agent mid-sentence, change topics, or correct themselves. The AI listens, pauses, and adapts — just like a human would.

22 Indian languages + code-switching

Hindi, Tamil, Telugu, Bengali, Marathi, Kannada, Punjabi, Gujarati and more. Customers can start in Hindi, switch to English mid-call — the agent keeps up.

Tool calling + live data lookups

Agent checks order status in Shopify, pulls appointment availability from Calendly, processes a Razorpay refund — all inside the live call.

Sub-500ms latency

Streaming STT + streaming LLM + streaming TTS. Customers feel they're talking to a fast, crisp voice — not dialing into 2005-era IVR.

PCI-ready call recording

Encrypted call recordings, PII redaction in transcripts, configurable retention, and a BAA for healthcare. SOC2 compliant throughout.

Seamless human handoff

When the AI hits an escalation trigger, it warm-transfers to your team with full call context, transcript, and customer record attached.

Use Cases

AI voice agent use cases

Inbound, outbound, and everything in between.

Customer calling support
Inbound support

Replace your IVR with a real conversation

Customers dial in and say 'I need to check my order status' — the AI agent authenticates, pulls the order from your CRM, reads back the shipping update, and handles the follow-up question — all in the customer's language, in under 90 seconds.

Result

6-minute IVR flow compressed to 90 seconds.

Sales team calling leads
Outbound sales

AI SDR that dials, qualifies, books

Upload a lead list. The AI agent dials, qualifies by BANT, books calendar slots, and drops detailed notes into your CRM. Your human SDRs only show up to qualified meetings — not cold outreach.

Result

10x dial volume at 1/4 the cost per qualified meeting.

Calendar booking
Appointment scheduling

24/7 booking, reminders, rescheduling

Patients, students, or clients call to book, reschedule, or cancel. The agent checks real availability, books the slot, sends SMS/WhatsApp confirmations, and handles reschedules when life happens.

Result

30% more bookings captured outside business hours.

Financial reminder call
Collections & reminders

Empathetic, compliant payment reminders

The AI agent calls customers with overdue invoices — in their language — explains the situation, takes partial payments, and offers payment plans. Compliant with RBI guidelines and trained on empathetic conversation patterns.

Result

40% higher recovery rate vs DTMF IVR systems.

E-commerce order verification

Prepaid & COD confirmation calls

Before dispatching high-value orders, the agent calls the customer to confirm delivery address, time slot, and COD intent. Fraudulent orders caught before they ship — and you save reverse-logistics cost.

Result

55% lower RTO (return-to-origin) rate.

Healthcare provider
Healthcare intake

Pre-visit screening & follow-ups

Before a hospital visit, the AI agent calls patients to collect symptoms, medication lists, and insurance details. Post-visit, it follows up on recovery, medication adherence, and prescription refills.

Result

50% less front-desk time per patient.

FAQ

AI voice agent questions, answered

An AI voice agent is software that answers or makes phone calls, understands what a human caller is saying in natural language, and replies with a natural-sounding voice — in real time. Unlike traditional IVR ('press 1 for sales'), an AI voice agent uses speech-to-text, a large language model (LLM), and text-to-speech in a streaming pipeline so conversations feel like talking to a person. CallMissed's AI voice agent runs in 22 Indian languages and supports code-switching (e.g. mixing Hindi and English in one call).
