A virtual phone number is a telephone number that isn’t tied to a specific phone line or physical device. Instead, calls to the number are routed through a telecommunications network and forwarded to one or more destinations such as mobile phones, desk phones, or cloud phone systems.
Virtual numbers allow businesses to manage incoming calls more flexibly while maintaining a professional contact number for customers.
Many Australian businesses use virtual numbers such as 1300 numbers and 1800 numbers to create a national contact point while routing calls to their team anywhere.
How Virtual Phone Numbers Work
When a customer dials a virtual phone number, the call is handled by a telecom network rather than a traditional fixed phone line.
The process typically works like this:
- A customer dials your virtual number.
- The call reaches the inbound number network.
- Call routing rules determine where the call should go.
- The call is forwarded to the appropriate phone or team.
The call can be routed to:
- Mobile phones
- Office desk phones
- Remote workers
- Call centres
- Voicemail systems
Because the number itself is virtual, businesses can update routing rules at any time without changing the number customers call.
Types of Virtual Phone Numbers
Virtual numbers come in several formats depending on how businesses want customers to contact them.
1300 Numbers
A 1300 number provides a single national contact number that customers can call from anywhere in Australia.
Calls to 1300 numbers are charged to the caller at a local call rate from landlines, while businesses pay for inbound call charges.
1300 numbers are widely used by businesses because they:
- Create a professional image
- Make advertising easier with one national number
- Allow advanced call routing

1800 Numbers
1800 numbers are toll-free numbers where the business pays the full cost of the call.
This means callers can contact the business without paying call charges.
1800 numbers are often used by:
- customer service centres
- national brands
- support lines

Local Virtual Numbers
Some businesses use local geographic numbers (such as Sydney or Melbourne numbers) that route to virtual systems.
This allows companies to appear local while operating from different locations.
Benefits of Virtual Phone Numbers
Virtual numbers offer several advantages compared with traditional phone lines.
Flexibility
Calls can be routed to any device or location. This makes it easy for teams to work remotely while still receiving business calls.
Professional Image
Virtual numbers provide businesses with a dedicated contact number instead of relying on personal mobile numbers.
A national number such as a 1300 number can make even small businesses appear more established.
Advanced Call Routing
Modern systems support features such as:
- simultaneous ringing
- IVR phone menus
- time-of-day routing
- geographic routing
- call recording
- call reporting
These features allow businesses to manage high volumes of calls more efficiently.
Scalability
As businesses grow, additional staff or locations can be added to the routing rules without needing new phone numbers.
The same number can continue to be used for years even as the business expands.
Example Business Setup
A small business might configure a virtual phone number like this:
Customer dials the company’s 1300 number
↓
IVR menu plays
Press 1 for Sales
Press 2 for Support
↓
Calls ring the appropriate team members
↓
If nobody answers within 20 seconds, the call forwards to a mobile phone or voicemail.
This type of setup ensures customers can always reach the business.
When Businesses Should Use Virtual Phone Numbers
Virtual phone numbers are commonly used by:
- small businesses
- national service companies
- remote teams
- call centres
- growing businesses that want a professional contact point
