The Technical Side of Inbound Numbers: How They Work

Discover how inbound numbers like 1300 and 1800 work, enhancing business communication through cloud-based systems, VoIP, and integration with business tools.

Most of us, at one time or another, have phoned a company that uses an inbound number such as 1300 or 1800 as its main point of contact.

Since they were introduced in the 90s, inbound numbers have become a vital part of modern business communications, as companies want their customers to be able to reach them as easily and efficiently as possible.

But have you ever stopped to wonder how they actually work?

In this post, we’ll explore the technical side of inbound numbers, covering aspects like their setup, routing mechanisms, how they can integrate with business tools, and the overall benefits they bring to companies of all sizes.

What Are Inbound Numbers?

Inbound phone numbers are cloud-based numbers that allow businesses to receive incoming calls and forward them on to any location or device.

They can be referred to by a range of terms, including:

• Cloud phone numbers

• Virtual numbers

• Internet phone numbers

• VoIP numbers

• Hosted phone numbers

• SIP numbers

In Australia, these numbers are available from companies like Teleca.

How do Inbound Numbers Differ from Landline Phone Numbers?

The main difference between landline and cloud-based phone numbers is how they deliver calls to you.

For instance, landline numbers use the traditional telephone network run by Telstra, and as they are assigned to a specific phone line or fixed device, they are only linked to one location.

This differs from inbound numbers, such as those that start with the prefix 1300, which use the internet and VoIP technology to connect calls around the world.

Inbound numbers are linked to a specific account (as opposed to one line, device, or location), which means businesses can receive calls from anywhere.

How Do Inbound Numbers Work Technically?

Inbound numbers rely on a complex telecommunications infrastructure to ensure all calls are received, routed, and managed efficiently.

Here is an overview of how they function.

1.  Call Routing

When a customer dials an inbound number, the call is not necessarily connected to a single fixed phone. Instead, businesses can configure call routing rules that determine where the call is directed.

Some of the more common call routing methods include:

• Interactive Voice Response (an automated system that guides callers using voice commands or keypad inputs)

• Direct routing (to a designated phone number)

• Geographic Routing (based on the caller’s location)

• Time-Based Routing (based on time zones or business hours)

• Skill-Based Routing (to the person most qualified to address the query)

By redirecting incoming calls to landlines, mobile phones, or VoIP systems in this way, businesses make themselves available to customers at all times.

2. Cloud-Based Infrastructure

As modern inbound numbers operate on cloud-based systems, they are extremely flexible and scalable.

For instance, cloud-based inbound numbers can enable remote teams to receive calls from anywhere, which reduces the need to pay for physical phone lines.

Additionally, they can offer businesses advanced features like call analytics, voicemail transcription, and integration with CRM tools to enhance their productivity and efficiency.

3. Integration with Business Tools

The great thing about inbound numbers is that they are not standalone entities but rather can be integrated with essential business tools.

These include CRM Systems that automatically log calls, track customer interactions, and improve follow-ups, and helpdesk software, which enhances customer support by linking inbound calls with tickets and case histories.

They can also integrate with e-commerce platforms to better support and manage enquiries and product-related questions and measure the effectiveness of specific marketing campaigns through analytics.

4. VoIP and SIP Technology

Many businesses use Voice over Internet Protocol (VoIP) and Session Initiation Protocol (SIP) to manage their inbound calls because they provide greater cost savings and more flexible call management than traditional phone lines.

For instance, VoIP enables businesses to receive calls on any internet-connected device, as opposed to a fixed line or location.

At the same time, SIP trunking allows multiple inbound numbers to be managed under one system, which, therefore, helps companies to scale and be more efficient.

The Benefits of Inbound Numbers for Businesses

Now that you know how inbound numbers work, it’s worth briefly mentioning why many businesses have adopted them.

Here are some of the main benefits associated with them.

1. Better Customer Experience

Inbound numbers make it much easier for customers to contact businesses.

Moreover, through features like IVR, call routing, and automated responses, they can reduce wait times and go a long way toward improving resolution rates and customer satisfaction.

2. Look More Professional

Customers tend to view companies that use inbound numbers as more professional, established, and trustworthy.

Subsequently, they are more likely to call them if they have a query they need answered.

3. Cost Efficiency

With VoIP-based inbound numbers, businesses can reduce their telecommunications costs by eliminating the need for physical phone lines and reducing international call fees.

4. Better Reporting

Inbound numbers come with call analytics data that can help businesses track various metrics that can improve their overall performance.

These include the number of calls they received, when the most and least calls come through, where customers are calling from, and if their enquiry was resolved satisfactorily.

With this information, they can improve call wait time by rostering more staff during busier periods. They can also create geographically targetted marketing strategies to increase brand awareness in specific locations.

5. Helps your business to scale

If your business is growing, inbound numbers provide you with a way to do so more seamlessly without confusing customers with different phone numbers.

With inbound numbers, you can use call routing and cloud-based features to direct calls more efficiently and between different departments or geographic locations.
