Inbound call routing is one of the most powerful features of modern business phone systems. Instead of every call ringing a single phone, inbound numbers allow calls to be intelligently directed to the right person, team, or location.
Businesses across Australia use 1300 numbers and 1800 numbers to manage incoming calls more efficiently while providing a better customer experience.
In this guide we explain how inbound call routing works, how virtual numbers handle incoming calls, and the most common routing methods used by businesses.
What Is Inbound Call Routing?
Inbound call routing is the process of directing incoming calls to the most appropriate destination.
Instead of calls always ringing a single phone line, routing rules determine where the call should go based on conditions such as:
- Time of day
- Caller location
- Team availability
- Department selection
This allows businesses to manage high volumes of calls while ensuring customers reach the right person quickly.
Inbound routing is commonly used with 1300 numbers, 1800 numbers, and other virtual phone numbers.
How Virtual Phone Numbers Work
A virtual phone number is not tied to a specific phone line or device.
Instead, the number exists within a telecom network and forwards calls to one or more destinations.
For example, when a customer dials your 1300 number:
- The call reaches the inbound number network.
- Routing rules are applied.
- The call is forwarded to the appropriate destination.
This could be:
- A mobile phone
- An office phone system
- A remote team member
- A call centre
- A voicemail system
Because the number is virtual, businesses can change routing rules at any time without changing the number customers call.

Common Call Routing Methods
Modern inbound phone systems offer several routing options that allow businesses to manage calls efficiently.
Simultaneous Ring
With simultaneous ring, multiple phones ring at the same time.
The first available team member can answer the call, ensuring customers are not left waiting.
This is commonly used by:
- Small teams
- Sales departments
- Support desks
Time-of-Day Routing
Calls can be routed differently depending on business hours.
Example routing setup:
Business hours → Office phones
After hours → Voicemail or mobile
This ensures customers can still reach the business even outside normal operating hours.
IVR Phone Menus
IVR (Interactive Voice Response) allows businesses to create automated phone menus.
Example:
Press 1 for Sales
Press 2 for Support
Press 3 for Accounts
IVR menus allow callers to direct themselves to the correct department, reducing call transfers and improving efficiency.
Geographic Routing
Geographic routing directs calls based on the caller's location.
For example:
NSW callers → Sydney office
VIC callers → Melbourne office
QLD callers → Brisbane office
This allows national businesses to route customers to the nearest team or location.
Example Business Call Flow
Here is a simple example of how inbound routing might work for a business using a 1300 number.
- Customer dials the company’s 1300 number.
- The IVR menu plays:
- Press 1 for Sales
- Press 2 for Support
- If the caller selects Sales, the call rings three sales representatives simultaneously.
- If nobody answers within 20 seconds, the call overflows to a mobile phone.
- After hours, calls go directly to voicemail.
This type of setup ensures every call has the best chance of being answered.
Benefits of Inbound Call Routing
Businesses use inbound routing because it improves both customer service and internal efficiency.
Faster Response Times
Calls are routed to the first available team member, reducing wait times.
Better Customer Experience
Customers reach the correct department faster, which reduces frustration and improves service quality.
Flexible Remote Work
Calls can be routed to mobile phones or remote workers, allowing teams to work from anywhere.
Scalability
As businesses grow, additional team members or locations can easily be added to routing rules.
The phone number itself never needs to change.
