AI

AI voice agents that answer every lead in under 30 seconds.

Voice agents built on Vapi that answer inbound leads around the clock, qualify them against the criteria you set, book straight into calendars, chase no-shows and revive dormant leads, across phone, WhatsApp and email. Everything writes back to your CRM, so the pipeline reflects what actually happened.

  • Vapi
  • Email
  • Calendar booking
  • Zoho / HubSpot / Salesforce / Odoo / Dynamics
  • Arabic & English

01 — The problem

Why this usually goes wrong.

Most inbound leads wait hours for a reply, and many never get one. Speed to lead decides who wins most inbound deals.

Hiring people to answer every enquiry around the clock is expensive, and they still miss calls at peaks.

How it runs

From first message to booked meeting, written to the CRM.

  1. 01

    Inbound

    WhatsApp, web form, email, ad lead form or phone call.

  2. 02

    < 30 s reply

    The AI responds in your tone and language, Arabic or English.

  3. 03

    Qualify

    Asks your criteria: budget, timeline, location, service, decision-maker.

  4. 04

    Route

    Qualified leads go to the right rep by territory, product or round-robin.

  5. 05

    Book

    Live calendar availability, confirmation and reminders sent.

  6. 06

    Write back

    Transcript, answers, score and booking saved to the CRM record.

No-show recovery

When a booked lead misses the meeting, the AI follows up within minutes, offers new slots and keeps trying on a schedule you set until they rebook or opt out.

Dead-lead revival

We run your existing database (old enquiries, lost deals, expired quotes) through a re-engagement campaign. Anyone who replies is re-qualified and booked like a new lead.

Human hand-off

Any conversation can be handed to a person instantly, by rule (high-value, complaint, specific keywords) or on request. The rep sees the full transcript.

Guardrails

The AI only answers from approved content and your pricing rules. It never invents prices, discounts or commitments, and every conversation is logged for review.

Scope

What we set up

Channels

WhatsApp Business API number, inbound voice line or call forwarding, shared inbox for email, and your website and ad lead forms.

Qualification logic

Your criteria written as explicit rules and scoring, not left to the model’s judgement. Disqualified leads get a polite close and are tagged in the CRM.

Calendar & routing

Google or Microsoft 365 calendars, round-robin or territory routing, buffers, working hours and public holidays.

CRM write-back

Native integration with Zoho, HubSpot, Salesforce, Odoo or Dynamics: contact, lead source, answers, score, transcript and meeting.

Reporting

Response time, qualification rate, bookings, show rate and revived leads, reported per channel and per campaign.

Plainly

Not a chatbot. Not an IVR tree.

WHAT IT IS NOT

Not a chatbot

A chatbot waits on a website for someone to type. A voice agent calls the lead back within seconds of the form, takes inbound calls, and holds a spoken conversation with interruptions and follow-up questions.

WHAT IT IS NOT

Not a recorded IVR

There is no “press 1 for sales”. The caller speaks normally, in English or Arabic, and the agent understands intent, asks your qualifying questions in the order the conversation allows, and books the slot.

WHAT IT IS

A voice agent wired into your pipeline

A Vapi assistant with your script, guardrails and tools: live calendar lookups, CRM search and update, SMS or WhatsApp confirmations, and transfer to a person when the rules say so.

How it is built

Built on Vapi, configured for your rules.

Vapi assistant

Each agent is a Vapi assistant: a system prompt holding your qualifying criteria and tone, a transcriber, an LLM and a synthesised voice, with first-message and end-of-call behaviour set explicitly. Model and voice are chosen for latency and Arabic or English quality, then tested on recorded sample calls.

Phone numbers & telephony

Numbers are provisioned through Twilio or Vonage, or calls are forwarded from your existing 3CX, RingCentral or Aircall line over SIP. Outbound speed-to-lead calls are triggered by a webhook from your web form, Meta lead ads or CRM.

Tools the agent can call

Server-side functions the agent invokes mid-call: check calendar availability, create the booking, look up the lead in the CRM, update qualification fields, and send a WhatsApp or SMS confirmation. Each function is logged with inputs and outputs.

Write-back

At end of call Vapi posts the transcript, recording URL, summary and structured qualification answers to our endpoint, which writes them to the lead in Zoho, HubSpot, Salesforce, Odoo or Dynamics and sets the next task.

No-shows and dormant leads

Scheduled outbound campaigns call no-shows to rebook and work through old enquiries with a re-engagement script, within the calling hours and consent rules you set.

Cost and limits

Running cost is per minute (Vapi platform, telephony, model and voice) and is estimated per call during the pilot. Very long or highly technical sales conversations still belong with your team; the agent books them in.

Straight answer

What it won’t do

It won’t close complex deals. It gets the right people into a meeting with your team faster, which is where most leads are lost.

It is only as good as your qualifying rules and the content it can answer from. We spend real time on both before launch.

WhatsApp Business API has template and opt-in rules set by Meta. Outbound re-engagement has to follow them, and we design campaigns to stay compliant.

04 — Typical effort

What it usually takes.

Ranges from comparable projects. You get a fixed-scope quote after a 30-minute call.

Single channel, one calendar3–4 weeks
Phone, WhatsApp and email, multi-team6–8 weeks
Dormant lead revival campaign2–3 weeks

05 — What you own

Yours at handover.

  • Vapi assistants in your account
  • Phone numbers in your name
  • Prompts, scripts and guardrails
  • Call transcripts and reports

FAQ

Questions we get about AI lead qualification

Does it work in Arabic?

Yes. Conversations can run in Arabic or English, detected from the lead’s first message, with qualifying questions and answers approved in both languages.

Which CRMs does it write to?

Zoho CRM, HubSpot, Salesforce, Odoo and Dynamics 365 natively. Other systems are possible through their API.

Can it take phone calls?

Yes. A voice agent can answer inbound calls or call back web leads within seconds, ask the same qualifying questions and book a meeting, with a recording and transcript on the CRM record.

Will leads know they are talking to AI?

We recommend disclosing it, and most clients do. Leads care more about getting an immediate, useful answer and a booked slot than about who sends it.

How quickly can it go live?

A single-channel setup with one booking calendar usually goes live in a few weeks. Multi-channel, multi-team routing takes longer. The fixed-scope quote states the timeline.
