Overview

What is IVR & Conversational AI?

Dollu’s IVR and Conversational AI service covers the whole spectrum of automated voice, from a well-designed touch-tone menu that gets callers to the right queue in two key presses to a natural-language voice bot that authenticates a customer, checks an order and reschedules a delivery without an agent. Everything runs on our voice platform, so it works in front of Dollu CCaaS, an existing contact centre, a Teams or SIP-connected PBX or a raw SIP trunk, and it uses inbound numbers we already hold in 110+ countries.

The visual builder is a browser canvas where business users drag menus, prompts, data look-ups, decisions and transfers into a flow, test it against a phone number and publish it with version control and instant rollback. Prompts can be recorded, generated with neural text-to-speech in dozens of voices, or synthesised on the fly from CRM data. Speech recognition replaces key presses with spoken answers, and every node can call an API, a webhook or a database, so balance enquiries, order status, appointment booking and payments become fully automated flows rather than routing hints.

Conversational AI adds intent understanding on top. NLU models trained on your own call data recognise what a caller wants in more than 30 languages, including Hindi, Hinglish, Arabic, Bahasa and the major European languages, and handle interruptions, corrections and mixed-language speech. For open-ended dialogue we deploy LLM-based agents inside guardrails: retrieval grounded in your knowledge base, strict tool permissions, response validation, PII redaction and topic boundaries, so the bot answers from your policies and never invents an offer or a refund it cannot honour.

Automation only works if the exit is graceful. When a caller asks for a person, hits a confidence threshold or reaches a policy boundary, the conversation transfers to a live agent with the full transcript, intent, collected data and sentiment attached, so nobody repeats their account number. Analytics show containment, intent volumes, drop-off points, misrecognitions and cost per contact, and our conversation designers review the flows with you monthly, because the fastest way to raise self-service rates is to fix the three intents callers abandon most.

Why Dollu

Why choose Dollu for ivr & voice ai.

The advantages of buying from a carrier that owns its network, interconnects and operations - rather than a reseller.

  • Answer instantly, around the clock

    Balance checks, order status, bookings and password resets are handled in seconds at 3 a.m. on a public holiday, with no queue and no overtime.

  • Lower cost per contact

    Every routine call the bot completes costs a fraction of an agent-handled one, and calls that do reach an agent arrive identified, classified and shorter.

  • Speak every customer’s language

    Speech recognition, NLU and text-to-speech in more than 30 languages, including Indian and South-East Asian languages that many vendors treat as afterthoughts.

  • AI you can put in front of customers

    Grounded answers, tool permissions, response validation and topic limits keep LLM-based agents on policy, with full transcripts for audit and a human always one request away.

  • Compliance and privacy controls built in

    PII redaction in transcripts and logs, PCI-compliant payment steps, regional data storage, consent prompts and retention policies aligned to GDPR and sector rules.

How it works

How it works.

From first conversation to live traffic - a tracked, engineer-led onboarding with a named owner at every step.

  1. Step 01

    Map intents

    We analyse a sample of your calls and existing IVR data to rank the intents by volume and automation potential, and agree the first set to build.

  2. Step 02

    Build

    Flows, prompts and bots are built in the visual designer, connected to your systems and tested against real numbers, with your team trained to make changes themselves.

  3. Step 03

    Pilot

    A share of traffic is routed to the new flows with close monitoring of containment, hand-offs and caller feedback; prompts and models are tuned before full roll-out.

  4. Step 04

    Optimise

    Analytics and monthly design reviews identify the next intents to automate and the prompts to fix, so containment rises and cost per contact falls quarter on quarter.
