Voice over Internet Protocol (VoIP) systems have revolutionized the way businesses communicate. They offer a cost-effective and efficient means of communication that allows for easy collaboration between teams and remote workers. However, VoIP systems are also vulnerable to hacking. Hackers can exploit security weaknesses in VoIP systems to gain unauthorized access to sensitive business information or use the system for malicious purposes. In this blog, we will discuss five signs that your VoIP system might be hacked and what you can do about it.

Unusual Call Patterns

One of the most obvious signs that your VoIP system might be hacked is unusual call patterns. Hackers may use your system to make unauthorized calls, often to premium rate numbers or international destinations, resulting in higher bills than usual. These calls are usually made during off-hours or weekends when they are less likely to be noticed.

What to do: Monitor your call logs regularly and investigate any unusual call patterns. Consider implementing call restrictions to prevent unauthorized calls from being made.

Poor Call Quality

Hackers may also use your VoIP system to make spam calls, resulting in poor call quality. These calls may be automated and may result in frequent dropped calls, echoes, or background noise.

What to do: Implement spam filtering to block unwanted calls. Update your system software regularly to ensure that it is equipped with the latest security features.

Unauthorized Access to Your System

Hackers may attempt to gain unauthorized access to your VoIP system by guessing passwords, exploiting vulnerabilities in your system, or using phishing scams to trick users into revealing their login credentials.

What to do: Implement strong passwords and two-factor authentication to prevent unauthorized access to your system. Educate your employees on the dangers of phishing scams and provide training on how to recognize and avoid them.

Unusual Network Activity

Hackers may also use your VoIP system as a gateway to access other systems on your network. This can result in unusual network activity, such as spikes in data usage, unusual traffic patterns, or unauthorized access to other systems.

What to do: Monitor your network activity regularly and investigate any unusual activity. Implement firewalls and other security measures to prevent unauthorized access to your network.

Changes in System Settings

Hackers may also make changes to your VoIP system settings, such as call forwarding, voicemail settings, or auto-attendant settings.

What to do: Regularly check your system settings to ensure that they have not been changed without your knowledge. Implement access controls to prevent unauthorized changes to your system settings.

VoIP systems offer a great way to communicate with your team and customers, but they also pose security risks. By monitoring your system for the signs of a hack and implementing the necessary security measures, you can protect your business from the risks of VoIP system hacking. Stay vigilant and stay secure!
