What Are Virtual Phone Numbers?
Virtual phone numbers are phone numbers that exist in the cloud rather than being tied to physical telephone lines or specific locations. When someone dials a virtual number, the call routes through internet-based systems to whatever destination phone you’ve specified—mobile, landline, or VoIP—regardless of where that phone is physically located. This virtual nature provides flexibility impossible with traditional phone systems.
Unlike standard phone numbers tied to specific telephone exchanges and physical locations, virtual numbers can operate from anywhere. A business in Brisbane can use a Sydney-area virtual number. A home-based sole trader can present a professional business presence without revealing their personal mobile number. Multi-location businesses can use one national number that routes to appropriate locations automatically.
In Australia, 1300 and 1800 numbers are the most common types of virtual business numbers. For complete details about how these work, see our guides on how 1300 numbers work and how 1800 numbers work.
How Virtual Phone Numbers Work
Virtual numbers operate through VoIP (Voice over Internet Protocol) technology and intelligent routing systems. When someone calls your virtual number, the call enters the telecommunications network and is directed to a virtual exchange in the cloud. This exchange reads your configured routing rules and forwards the call to your destination number—the process happens in milliseconds, so callers experience no noticeable delay.
You manage your virtual number entirely through an online portal accessible from any device with internet access. Update where calls are routed, change business hours, record new greetings, set up IVR menus, or adjust any setting instantly. Changes take effect within seconds without requiring technician visits, hardware changes, or coordination with telecommunications providers.
The virtual system enables advanced features impossible or expensive with traditional phone lines: route calls to multiple numbers simultaneously, forward to different destinations based on time of day, direct calls geographically based on caller location, implement failover routing to ensure calls are always answered, and record all calls for quality and training purposes.
Virtual numbers provide professional presence regardless of business size. Sole traders working from home can present as established businesses with professional phone systems. The caller experience—custom greetings, IVR menus, professional voicemail—mirrors what large corporations provide, helping small businesses compete for customer trust and credibility.
Location flexibility is a major advantage. Businesses can move offices, expand to new locations, or transition to remote work without changing their phone number. Update routing in the portal and calls follow you wherever you go. This is particularly valuable in modern work environments where teams are distributed or businesses operate without fixed offices.
Cost efficiency compared to traditional phone systems is significant. Virtual numbers require no hardware purchase, no installation costs, no technician callout fees, and no maintenance contracts. Plans typically start at $10-30 monthly with no setup fees or long-term commitments. Scale up or down instantly without purchasing new equipment or dealing with complex telecommunications contracts. For pricing details, see 1300 number costs.
Australia offers several types of virtual phone numbers for different business needs. 1300 numbers operate on a cost-sharing model where customers pay local call rates and businesses pay connection costs. These provide professional national presence at affordable operating costs, making them popular for general business lines, sales enquiries, and appointment bookings.
1800 numbers are toll-free for callers—customers call for free while businesses pay all call costs. These work well for customer service lines, support desks, and any function where removing cost barriers maximizes customer contact. The higher operating cost often justifies itself through increased call volume and improved customer satisfaction.
Local geographic virtual numbers (02, 03, 07, 08 area codes) provide local presence in specific cities or regions. A Melbourne-based business can have a Sydney virtual number to appear local to Sydney customers. These numbers route to your actual location while presenting local presence where you want it.

Features Included with Virtual Phone Numbers
Modern virtual phone numbers include comprehensive business phone features at no extra charge. Call forwarding routes calls to any Australian phone number you specify. Advanced routing includes time-based forwarding (different numbers at different times), failover routing (tries multiple numbers in sequence if first doesn’t answer), and geographic routing (routes based on caller location).
IVR (Interactive Voice Response) menus provide self-service options: ‘Press 1 for Sales, Press 2 for Support.’ This professional feature was traditionally available only to enterprises with expensive phone systems. With virtual numbers, it’s included in plans starting at $10 monthly. Voicemail with email delivery ensures you never miss messages—recordings arrive in your inbox for listening from anywhere.
Call recording captures conversations for quality assurance, training, and compliance. Detailed call reporting shows who called, when, from where, how long they stayed on the line, and which team member answered. This data supports marketing attribution, operational optimization, and performance management. For comprehensive reporting features, visit our call reporting page.
Getting Started with Virtual Phone Numbers
Starting with a virtual phone number is straightforward. Browse available numbers from your provider’s inventory, selecting based on memorability, pattern, or specific digit combinations. Choose a monthly plan matching your expected call volume—most businesses start with entry-level plans and upgrade as needs grow. Complete payment and your number activates within minutes.
Configure basic settings through your online portal: specify where calls should route, set business hours, record a greeting. These basics get you operational immediately. As you become familiar with the system, add advanced features: IVR menus, failover routing, geographic routing, or integration with business systems like your CRM.
The beauty of virtual numbers is you can start simple and add complexity only when needed. Begin with basic call forwarding to your mobile. Add a second destination number for failover. Implement business hours routing. Set up IVR menus. Each feature adds incrementally without requiring system changes, new hardware, or service interruptions. To get started, learn about how to get a 1300 number or explore buying 1800 numbers.
