How Your Business Can Protect Your VoIP Phone System

Hacking and all sorts of dilemmas can potentially happen to your company’s VoIP phone system, so here are some crucial cybersecurity tips!

VoIP business phone systems are helping remote working everywhere!

There’s no denying just how many benefits your business can obtain from investing in a VoIP phone system, but there of course are cybersecurity risks associated with anything that’s connected to the Internet.

VoIP systems use Web connections, which subsequently can be infiltrated by third parties and cause significant hassles when you aren’t properly protected. The Data Talk team is always here to support your phone system’s cybersecurity needs, which is why we’ve detailed the following list of tips oriented around protecting your VoIP system from hackers.

So here are some of the features you should consider for your company’s VoIP phone system’s cybersecurity:


Firewalls offer comprehensive security for VoIP systems, which is why they’re considered a necessity in today’s cybersecurity industry. When you make a VoIP call with a firewall, a Session Initiation Protocol (SIP) will establish the connection and terminate the connection at the end of the call.

SIP is crucial for any VoIP system’s security, and you should also be frequently updating the operating systems on all of your team’s devices as well.

Making Strong Passwords, And Regularly Updating Them

Careful password handling is also very important for VoIP phone systems. This is why a lot of Web-connected platforms and software programs these days require 12-character passwords that include upper and lower case letters, numbers and special characters.

Some VoIP phones are set up with factory-set passwords that are often vulnerable to hacking, so you should establish customized passwords and change them at least a few times each year.

Network Monitoring

There’s absolutely no denying just how crucial network monitoring is for your VoIP security. Network monitoring is huge for showing you valuable data like traffic, as well as any strange anomalies.

Hackers also typically assume that businesses don’t monitor their data during weekend and nighttime hours, which is where the Data Talk team comes in to provide logistic and technology support that hackers can’t get around.

Using Virtual Private Networks (VPNs)

If your employees are working remotely within your VoIP system, then it could be a smart move to establish VPNs that will avoid the possibility of establishing corrupted connections. VPNs essentially develop virtual tunnels that help keep your data encrypted and your onsite networks secure.

And the good news is that when you team up with Data Talk for VPN services, we’ll be sure to provide you with a sufficient amount of bandwidth that guarantees call quality.

Using Data Encryption

VPNs aren’t the only encryption strategy your business should implement, because there are a few doors that can allow dangerous intruders into your system.

The first door is the one who initiates the call, as well as their device. The receiver of the call is also another door, and the third door is the intermittent data within each phone call.

Although VPNs can do a great job at securing these ports, you’ll also need other encryption layers for your voice conversations and valuable data. Hackers can’t exploit this encrypted data, even if they somehow figure out a way to intercept your calls.

Disabling Web Interface Usage

It’s also a smart idea to avoid using a Web interface within your company’s VoIP phone system, and this is because you’ll be opening your system up to new weakness areas when using desktops as phones.

What’s really alarming about this potential vulnerability is that one exposure from an external party can potentially impact all of your VoIP data. So if your team needs to use a Web interface to handle your calls, be sure to keep security strict!

Thoroughly Training Your Team

As mentioned in the above section, a lot of VoIP cybersecurity issues result from users being irresponsible. All of your team members need to understand just how important proper password handling is, as well as how to recognize unusual activity within your network.

That’s why it’s a good idea to organize training sessions on a periodic basis, so your team can keep your phone system’s security as tight as possible.

Avoiding International Calls

If your business doesn’t have to make international calls on a regular basis and you’re largely speaking with local customers, then you might want to disable your international calls option.

This is largely because hackers tend to want to make expensive international calls within a company’s phone system to save their own money, and they’ll take advantage of weak security when they can.
