Protect your VoIP systems against denial-of-service attacks

Telephony systems are crucial to business communications and operations and therefore need to be highly secure. Although malware and viruses are some of the most common threats to Voice over Internet Protocol (VoIP) systems, there are other little-known threats too, such as denial-of-service (DoS) attacks. If your business heavily relies on VoIP, you should learn how to protect it from DoS attacks.

Denial-of-service attacks

The end goal of any DoS attack is to overwhelm a system with so many requests that it is eventually forced to shut down. Telephony DoS (TDoS) attack is a subcategory leveled at VoIP systems. Alarmingly, this attack is commonly used against hospitals and 911 phone lines. Some TDoS attackers even demand a ransom to halt the attack, which is similar to ransomware attacks. They take advantage of cryptocurrencies and caller-ID spoofing to make it incredibly difficult to identify attackers.

TDoS attacks generally employ fewer resources than the DoS attacks that are designed to cripple IT systems, which include networks, servers, and software. At its most basic, a TDoS attack requires only an automated phone dialer that calls a target phone number and hangs up — over and over. That very simple strategy can stop anyone else from getting through the line.

What organizations need to do

While your first instinct may be to lock down your VoIP system with complicated security measures, doing so will only do more harm than good. Most businesses can’t operate if they can’t communicate with their customers, business partners, and other third parties.

Although VoIP may be a digital resource similar to other components within your IT systems, the very nature of phone lines makes hiding them behind firewalls and other protections impossible. Fortunately, there are now new security protocols that can protect your communication infrastructure against those who try to use force to gain access to your directory information. These protocols can also identify, reroute, and filter calls coming from known attackers. Get in touch with our team to learn more about these protocols.

If you’re experiencing any abnormalities with your VoIP system, or if you want to deploy the most advanced solution that the market has to offer, our expert team of IT professionals is ready to help you at the drop of a hat — just call today.

Should your business switch to VoIP phones?

Many businesses still rely heavily on landline telephones as the first point of contact with their customers. But thanks to technological advances that combine the best of traditional telephony and digital connectivity, businesses can now enjoy a more affordable and more reliable option: Voice over Internet Protocol (VoIP) phones. Does this technology fit your business? Read on to find out.

What is VoIP?

Traditional telephones are still very much a part of today’s business operations, and companies use them to connect with various stakeholders such as customers, investors, and suppliers. But telephony has come a long way from when the first telephone was invented in 1876. Modern phone systems are now automated, cheaper than ever to acquire, and have virtually unlimited reach. One of the most widely used modern phones in the market today is the VoIP phone.

VoIP technology uses the internet instead of wired circuits to transmit data. And it does more than just transmit audio like legacy phones do. It can also send a variety of data (e.g., video, multimedia, SMS, etc.) and perform other tasks such as call routing and anonymous call rejection.

VoIP setups: On-premises vs. hosted

A VoIP system’s hardware and software can be either on-premises or hosted. On-premises means that all of the VoIP’s components are housed within the premises of the company. Hosted VoIP, meanwhile, means that only some of the hardware, like phone units and other equipment, can be found within a business’s premises. The rest of the technology, including the software, is hosted online. In this setup, service providers look after hosted systems for their clients.

Which setup should you choose? You may want to consider the condition of VoIP hardware and software in different environments.

Generally, hardware is affected by the wear and tear stemming from daily use, so whether you choose to house it on-premises or not doesn’t make much of a difference. Barring any accidents or physical damage, any VoIP hardware should last several years.

On the other hand, software requires regular updates and security patches, and it’s faster and cheaper to update software that’s hosted in the cloud versus one that’s on-premises. If you want to better protect your systems from cyberattacks and enjoy the latest VoIP features as soon as they come out, choose hosted VoIP.

Business adaptability with VoIP

In the past, hardware and software were built to last. Traditional phone systems, for instance, rarely get new features once they’re deployed. Meanwhile, modern IT solutions like VoIP are built to adapt and change.

These days, critical updates are released regularly, with complete overhauls taking no longer than 2–3 years. If you choose hosted VoIP technology and outsource its management, then you can enjoy a faster, easier, and cheaper upgrade via cloud-based rollouts.

Most hardware components are also improved upon every once in a while, with replacements and upgrades coming every 5–8 years on average. Note that if you outsource your VoIP systems, your VoIP provider will be the one to ensure that the hardware is up to date, and your company won’t have to shoulder outright hardware upgrade costs.

As your business moves forward, you must have a phone system that is agile and fast, and can integrate smoothly with the other systems in your business, such as email or management software.

Be one step ahead

VoIP is reliable. As long as you have a high-speed internet connection, you can guarantee high-quality voice calls with 99.9% connection uptime. Unavailability, choppy connections, and other traditional phone issues translate to lost sales and productivity. If your phone service is spotty and is constantly unreliable, perhaps it’s time to switch to VoIP phones.

VoIP is reliable, adaptable, and won’t cause a dent in your budget. Call our experts today so you can always be a step ahead with VoIP.
