Call Blocking
Call blocking is a powerful feature that prevents unwanted calls, such as spam, scams, or robocalls, from reaching your business phone system. Your organisation can enable it through device settings, provider services or third-party apps.

How Call Blocking Works?
With scam calls on the rise in Australia, call blocking has become essential for safer and more efficient business communication. Solutions from providers like Telstra, along with dedicated call-blocking apps, protect Australian businesses against nuisance calls.
But how does it work? Call blocking identifies and stops unwanted calls using predefined rules or user settings. It works by filtering out specific numbers that have been marked as spam, scam, or unauthorised before they are sent to your phone.
There are two forms of call-blocking solutions. The first one is automatic blocking, which
uses AI and spam databases to filter suspicious calls automatically, saving you time and effort. The second type is manual call blocking. It allows you and your team to customise & add numbers to your business phone system’s blocklist for precise control.


Types of Call-Blocking Services
Carrier-Provided Call Blocking
Telecommunications providers like Telstra offer call-blocking services that automatically filter spam or scam calls before they reach your device. These services are integrated at the network level to provide a seamless experience for mobile and landline users.
Device-Specific Call Blocking
Many smartphones and landline phones have built-in features to block calls directly from their device. If your team uses their smartphones for work calls, they can access their settings to block blacklisted numbers or enable spam detection. Enabling call blocking on landline phone systems can be done through the service provider.
Third-Party Call Blocker Apps
Apps like Hiya, Truecaller, and RoboKiller offer real-time spam alerts and customisable blocklists. These apps are widely used in Australia and provide advanced call interception options to detect and stop unwanted calls.
How to Choose the Right Call-Blocking Solution?
When choosing a call-blocking solution, evaluate its advanced features to ensure it is compatible with your business communication needs and habits.
