Like any other tech application, voice over internet protocol (VoIP) technology is prone to various security risks and threats. If not properly protected, VoIP security will be compromised and everything in the system may be exploited by cybercriminals.

However, just because there are security threats does not mean hosted VoIP system is not reliable, or that Singapore businesses are better off with traditional telephone lines. In fact, there are a number of things you can do to safeguard your organization’s VoIP system.

1. Protect Account Information

One of the most common problems encountered by internet users is hacked accounts, which are likely caused by stolen passwords. With phones, sometimes all it takes is a single Google search to get hacked.

Usually, voip interfaces and devices come with default passwords that can be searched easily online. Most of these interfaces do not have automatic lockouts, making it easy for hackers to bombard the interface with unlimited combinations of keygen passwords. While this sounds impossible to block, using the best telephony system for businesses in Singapore greatly helps in keeping everything secured and intact.

When you have just acquired a new VoIP phone or you need to reset a phone to factory default, the first thing you need to do is to change the password. Otherwise, if you do not do so immediately, you will likely forget about it and compromise the security of the system. Some phones only require one password for both phone and web interface, while others require separate passwords. If yours is the latter, change both.

2. Disable Phone Web Interface

The web interface of IP PBX telephone system lets you access and update many VoIP properties, including the SIP and network settings, call settings, codecs and other VoIP features. The interface also lets you download phone backup configuration, which reveals the usernames and passwords of the telephone’s users in plain readable text.

The web interface of the IP PBX telephone system is probably the most vulnerable point of the entire VoIP system. It is very useful for company operations in the right context, but a prime target for cybercriminals who want to access your network for fraudulent acts.

Hackers do not need to connect on your phone’s LAN to gain access to your phone’s web interface. It can be done remotely over an open internet. All the hacker needs is your phone’s IP address, and voila! They can now control your VoIP usage. And even if your phone’s web interface is protected with a password, hackers can still discover your log in details by using a key cracking application.

That is why it is strongly recommended to turn off your IP phone’s web interface, and only re-enable it if you need to update the settings. But keep in mind that disabling the web interface varies from manufacturer to manufacturer. Consult your support staff or your hosted pbx service provide for a step-by-step instruction.

3. Disable International Calls

Many hackers hack their way to IP PBX telephone system for the purpose of fraudulent operations. They try to rack up your calling minutes for expensive charges. If you do not need to make regular long-distance calls, it would help to completely disable the international calling feature of your pbx phone system.

In times when you need to make a long-distance call, use a calling card to activate international calling. If part of your operations is making international calls on a regular basis, turn on the feature but make sure to monitor it proactively.

4. Use Anti-Virus Software

Since computers play an imperative role in a hosted VoIP system, protecting them against malware and other suspicious programs is part of crystal voice phone features offered to its Singapore users. Viruses and malware enter your phone system through email. Once opened, it will compromise your security features and interrupt—or worse suspend—your network services entirely.

Avoiding these unfortunate circumstances is as simple as installing and running anti-virus software, like firewalls. Most VoIP service providers in Singapore offer anti-malware protection as part of their service offerings.

5. Enable NAT Feature

Network Address Translation (NAT) is a router feature that provides computers, IP phones and other network devices with private IP addresses that can only be viewed on LAN. This masking feature will serve as barrier between the online traffic and your private IP phone. If the hacker will not be able to discover your IP address, then he cannot manipulate your VoIP activities.

Devices used for cloud VoIP that do not use NAT are prone to getting hacked. Hackers use apps and programs that let them search for endpoints that are not protected with NAT. A pbx phone system with public IP address may get ‘ghost calls’ or calls that only rings your device so the hacker can see what your IP device is. This is one of the first steps that hackers make to identify a target.

That is why it is extremely crucial to protect every cloud VoIP device with private IP address. This router feature is another layer of protection for your hosted pbx system from anyone trying to exploit it.

Alongside the evolving technology, network security threats become more advanced as well. Safeguarding your business data and customer information should always be your company’s top priority. You and everyone else in your network should always be vigilant in order to prevent inconvenient and costly security breaches. Partnering with a reliable VoIP service provider in Singapore and strengthening your security protocols augments your business’ ability to counteract these network threats.
