Dealing with voice network security and troubleshooting is an ongoing battle. As new features, capabilities and telecom products emerge, so do potential vulnerabilities and malicious users who may attempt to exploit them. Network and voice administrators must remain vigilant in ensuring security, privacy and confidentiality, which includes staying current with the latest in network troubleshooting and problem resolution.

This article is a review of the important security matters we’ve discussed over the past year, especially when it comes to network security and troubleshooting issues related to telecommunications services.

A key telecommunications trend today involves integrating multiple communications systems that were traditionally implemented separately. IP telephony, video and collaboration, and now security, access and facility management, are all converging into unified communications systems.

Grandstream has recognized and helped further this trend through innovative devices such as the GDS3712 IP video intercom system. In this article, we dig deeper into the capabilities of this device and how its use can simplify and enhance security and facility management.

Security is usually one of the top three concerns of most enterprises regarding telecom services. A properly enforced security policy is essential. It can protect against breaches that are capable of threatening organizational viability.

In this article, we share some best practices for creating and maintaining a network security policy and provide an easy-to-use downloadable template to help you create one for your enterprise.

Securing voice services is among the most essential measures any business can take to mitigate attacks involving toll fraud, denial of service or corporate espionage. Voice over Internet Protocol (VoIP) encompasses a robust and fully developed set of technologies that incorporate strong security features sufficient to deal with virtually all such attacks. Nevertheless, even with the most secured VoIP services, malicious hackers often find alternative attack vectors to achieve their goals.

In this article, we examine those attack vectors and the best practices to defend against them.

When you speak on the phone, it’s natural to believe that it’s a private conversation between you and the person on the other end of the line. However, do you know what mechanisms are employed to deliver this confidentiality? And how confident can you truly be in these security measures?

In this article, we take a detailed look at Voice over Internet Protocol (VoIP) security technologies and how they keep conversations confidential.

Experienced telecom administrators know it’s challenging to provide ironclad security while maintaining speed on a communications network. This is especially true for enterprises with large mobile workforces, where users have internal telephone extensions on their mobile devices or home computers.

To make achieving these essential goals easier, Grandstream has introduced UCM RemoteConnect. This service caters to provisioning extensions for remote users of on-premises UCM6300 IP PBXs securely and lightning-fast.

Telecommunications networks will always be targets of malicious attacks. One of the most vulnerable components of a telephony network may not be the technology, but people. Rather than targeting the phone system or data network, many attackers focus their fraudulent activities on the users themselves. In this article, we take a look at some of the most common telephony scams out there today, so you can be aware of them and do your part to protect your employees and your company from them.

As we celebrate Shark Week this week, we are reminded of the proverbial sharks faced by network engineers in the form of security breaches and technical issues. TeleDynamics has created a collection of resources to help you troubleshoot audio problems, secure your network, protect your telephone system from hackers, analyze voice packets, and more. In this article, we offer a compilation of some of our most popular resources, so you’ll have them handy. For each listing below, click on the blue heading to read the full article.

When we think about network security, the telephone network is often overlooked as a target by attackers. One of the most common forms of attack on a telephony network is what is known as toll fraud. The Communications Fraud Control Association (CFCA) reports that in 2019, toll fraud caused US$28.3 billion globally in losses, corresponding to 1.74% of global telecom revenues.¹ In this article, we look at how toll fraud affects both conventional telephony and modern VoIP systems, and what you can do to protect your business.

Telephony denial of service (TDoS) is a type of cyberattack that can be used to disable telephony systems. Similar in concept to a typical data network DoS (denial of service), its purpose is to deny users access to a particular telephony service. In this article, we discuss how TDoS attacks are conducted and what measures you and your telco can take to protect your systems.
