Customer case studyReal EstateAI Calling

From thousands of leads to qualified buyer appointments.

Voxworks gave a Sydney real estate team the capacity to call every new lead, revive its dormant database and keep following up when buyers went to voicemail or asked for a better time.

The client

Sydney house and land sales team

A small, relationship-led real estate team selling house and land packages in two highly competitive Sydney growth corridors (anonymised to protect commercially sensitive information).

The challenge

High lead volume, low connectivity.

The team already had demand but did not have the calling capacity to find purchase-ready buyers before a competitor did.

01

Speed to lead

The team was generating between 20 and 50 leads each day. Rex captured a short description for each one, but did not reveal who was ready to buy. A small sales team could not call every contact quickly enough to find out.

By the time an agent reached many leads, they were either not ready or had already purchased through someone else. In a non-exclusive property market, that delay meant the marketing investment was lost before a real conversation began.

02

Zero response over text

Automated email and SMS sequences were already in place, but response rates remained below one per cent. The channels were not creating the conversations needed to understand budget, finance position or purchase intent.

03

A dormant database

The database had grown to 6,500 leads. With new enquiries arriving every day, the team had no practical way to revisit older contacts even though some would now be ready to buy.

04

Wasted time dialling voicemail

At least half of the team’s calls reached voicemail. Around a quarter found the buyer busy or at work and needing a callback; others rang out or failed to connect. Agents were spending most of their calling time navigating availability rather than building relationships.

The Voxworks solution

Automated lead dialling pipeline

The CRM remains the source of truth. Voxworks imports each new contact, routes it to the list that matches its lead type, loads that list’s script, and lets the scheduler decide when to dial.

Rex CRM

New contacts are polled daily with the records needed to understand them i.e. leads, properties and the agent each one belongs to. Nothing is configured, exported or re-keyed inside Rex. The Rex ID is stored so that after every call the transcript, outcome, qualification answers and next action are written back to the same contact record.

From this live deployment

Daily Rex automation

Voxworks Automations polled Rex each day for new leads.

After each call, Voxworks returned the transcript, call outcome, qualification answers and next action to the same contact record after each conversation.

The team reviews the full call summary prior to the appointment directly within Rex.

Real world example

Returned call converted into a booked appointment.

This is a recent example from a real property outreach campaign, where over 1,500 contacts were called using this exact call script.

The results

Voxworks sorts qualified buyers from noise.

Across the reporting period, Voxworks placed 2,586 calls representing 25.2 hours of recorded call time. Voicemail accounted for 35.5% of call outcomes, proving the time-saving value of automated redial logic.

Among calls that were answered, more than 80% became conversations lasting longer than 30 seconds, enough time to clear the cold-call opening, establish relevance and gather useful buyer information.

The workflow gave the sales team a prioritised stream of qualified conversations and booked appointments, while Voxworks handled the repeated dialling needed to reach each buyer.

The team now has the confidence to increase marketing spend knowing that every lead will be handled by Voxworks.

Core Insights

Voicemail was the largest single outcome. Without automation, the team would spend much of its calling time leaving messages and deciding when to try each buyer again.

Voxworks Action

Detects the mailbox, delivers the approved message, schedules the next attempt and cancels it if the buyer returns the call first.

Key insights

What we learned from this project.

The value came from managing the full journey from first dial to qualified handoff, and properly handling the challenge of real world outbound dialling and scheduling.

  1. 01

    Reachability is a major problem for human callers

    Over 80% of the cumulative call time was spent on contacts that were either not available or not interested. More than 40% of calls did not connect with the intended buyer on the first attempt, including 35.5% that reached voicemail. Automated redials and callback scheduling removed that repetitive workload from the sales team without abandoning the lead.

  2. 02

    Customers prefer real conversations over text or email marketing

    Existing email and SMS outreach produced response rates below 1%. By contrast, more than 80% of answered calls became conversations lasting longer than 30 seconds. Our system politely and efficiently spoke to buyers that are actively looking at properties but were not responding to the deluge of email campaign marketing. Each call produced enough time to establish relevance, ask a few questions, respond to simple queries and understand the buyer’s position.

  3. 03

    Apple Screen is now a significant consideration for outbound campaigns

    Around 10% of our outbound calls were met by the Apple iPhone or Google Android new call screening features. Our AI Voice AI system was not properly configured to handle these flows. We have since installed Gatekeeper Mode into Voxworks, to allow a targeted message to be played to the Apple Screen and wait for the response.

  4. 04

    Reliable follow-up makes lead generation profitable

    Previously, the team was throwing money down the drain on Meta ads, because the follow-up was either slow or non-existant. With every new lead entering a managed calling workflow, the team could increase marketing activity without creating an equivalent increase in manual sales administration.

  5. 05

    AI Voice can reliably absorb lead qualification for any team

    In this case study we demonstrate that Voxworks is efficiently able to call a huge volume of contacts within a short space of time, deliver a message to work out if the offer is relevant to that buyer, and arrange an appropriate time for your team to connect. In 2026, it no longer makes sense to waste team resources on a task that can be performed by a system, when that time can be better spent on tasks that require human connection.
