    What We Offer

    Types of 3CX Phone Systems We Offer

    Fintech & Tech Startups

    Startups need to scale support and sales lines fast, often without an in-house IT team to manage it. A cloud 3CX system scales instantly, adding new users or lines in minutes, and gives sales leaders call analytics and reporting to track team performance without extra tooling.

    Real Estate

    High call volume from active listings, agents who need to take calls from the field, and enquiry calls that go unanswered while an agent is with a client all cost real estate agencies leads. 3CX solves this with a mobile app for on-the-go calling, call routing by listing or agent, and CRM lead pop so agents see who's calling before they pick up.

    Sectors We Serve in Sydney

    Beyond fintech and real estate, we support a wide range of Sydney businesses on 3CX:

    Retail & E-Commerce

    Order and enquiry line routing across warehouse, head office and customer service teams.

    SaaS & IT services

    Call analytics and support queues for teams running high volumes of customer calls.

    Financial services

    Call recording and compliance-ready logging for regulated advice and lending teams.

    Hospitality & events

    Booking line handling for venues managing high call volumes during peak periods.

    Case Study

    Sydney Real Estate Agency

    Illustrative example, pending client sign-off for a named case study.

    Problem: A growing Sydney real estate agency was missing an estimated 20% of enquiry calls during peak open-home hours, with no way to route calls to available agents.

    Solution: Aatrox implemented 3CX with mobile-first call routing by listing and agent, plus CRM lead pop for instant caller context.

    Result: Missed enquiry calls dropped by over 80%, with faster response times converting more leads into inspections.
