TeleDynamics Think Tank

While certain live events have been cancelled amidst the COVID-19 pandemic, many of them have been replaced with virtual counterparts that have taken place via videoconference. Some of these events have had hundreds or even thousands of participants. With such numbers, how do videoconferencing systems cope with the traffic load and processing power required?

In this article, we take a look at the concepts involved with the scaling of videoconferencing for large numbers of participants. We also examine some best practices to keep in mind that will help ensure the quality of the end user experience.

Much experience has been gained over the past year when it comes to distance education and learning. The systems required to enable it have quickly developed and have been extensively streamlined. One of the most successful vendors in this process has been Konftel with its award-winning video-capable conference phones.

With its new T3 series IP phones, Yealink continues its tradition of providing advanced yet cost-effective enterprise telephony solutions to businesses of all sizes. Packed with a plethora of features, these entry-level phones can satisfy both the voice network administrator and the budget coordinator of most organizations. Read on to find out more about what they have to offer.

The spike in remote working amidst the COVID-19 pandemic has caused videoconferencing systems and service usage to skyrocket at a dizzying pace. At the heart of these systems is what is known as a multipoint control unit (MCU). Knowing where your MCU resides, how many simultaneous participants it supports within a conference, and what kind of extra features it delivers is key to designing a videoconferencing network that will ensure people enjoy the best quality service possible.

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.

Over time, enterprises grow, technological requirements increase, and ICT (information and communications technology) infrastructure becomes more complex. This complexity adds administrative overhead, can result in an inconsistency of system performance, and increases the probability of downtime due to human error.

One way to manage this complexity is to use the concept of configuration management (CM). In this article, we describe configuration management and show you how it can help streamline your VoIP, data, and ICT infrastructure lifecycle as a whole.

When researching options for upgrading your telephony network or installing one from scratch, you may have come across FreeSWITCH. This is a freely available open-source application server for real-time voice communications of various types, including voice over IP (VoIP). In this article we examine FreeSWITCH to help you determine if it is right for you, and how it compares with Asterisk.

If you have been involved with telephony within the last decade, you will have heard of Asterisk as an open-source alternative to proprietary traditional and IP PBXs. If you’re considering Asterisk as a solution for your business, this article may be useful, as it will clarify what Asterisk is, how it can be implemented, and what kind of support you will need to ensure its viability as a solution.

Yealink announced that it has topped the list of SIP phone manufacturers with a 29.5% market share in 2019, giving it the number-one spot for the third year in a row, according to the latest Global Enterprise Communications Platforms and Endpoints Market report by Frost & Sullivan. In this article, we look at the products and innovations that have earned Yealink this coveted ranking.
