TeleDynamics Think Tank

For small voice networks with only a few dozen phones that exist on a single site, design considerations for digital signal processors (DSPs) will probably not keep you up at night. In fact, you may never have to think about them at all! But for larger multi-site networks, the placement of your DSP resources is important, since when not placed appropriately they could interfere with conferencing performance. In this article, we outline what you need to know to design your network so DSPs work the most efficiently for you.

Now that working from home and dispersed workforces have become the new norm, connecting employees’ or company-issued smartphones to the enterprise IP PBX offers several advantages, including the ability to reach employees via their direct inward dial (DID) landline numbers, even though they are physically off-premise.

The technology that enables this is called VoIP over cellular data networks. In this article we detail how to enable it, the advantages of doing so and some potential issues to watch out for.

When researching options for upgrading your telephony network or installing one from scratch, you may have come across FreeSWITCH.

While working remotely has been on the rise for more than a decade, the trend accelerated geometrically amidst the COVID-19 pandemic. As a result, telecom vendors and service providers are scrambling to satisfy the increased demand for remote collaboration services.

Luckily, technology is also moving fast to keep up. In this article, we review a new connector available in Microsoft AppSource that allows all Yeastar IP PBXs to fully integrate with Microsoft Teams, the software giant’s unified collaboration platform. This allows communications between dispersed team members to be even more seamless and efficient.

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.

Artificial intelligence is affecting every area of our life, and is increasingly playing a role in all types of technological developments. Business telephone systems are no exception. In this article, we take a look at how AI can enhance your call center technology.
