Why MPLS still matters for real-time communications

Posted by Daniel Noworatzky on Jun 11, 2025 10:11:00 AM

As more businesses shift to cloud-based communications and remote workforces become the norm, ensuring consistent performance across dispersed sites has become a top priority for telecom and UC providers. For installers and resellers tasked with deploying reliable real-time communications services like VoIP and UC, the choice of underlying network transport can make or break performance.

Multiprotocol Label Switching (MPLS) is not new, but it continues to play a critical role in meeting the low latency, high reliability, and QoS demands of these modern deployments. In this article, we examine the performance of MPLS in supporting real-time communications and why it remains a go-to solution for interconnecting geographically distributed infrastructure.

Essential steps for applying QoS on UC networks

Posted by Daniel Noworatzky on Aug 28, 2024 10:08:40 AM

Network services such as voice over Internet Protocol (VoIP), unified communications (UC), video conferencing, and collaboration systems are fundamentally dependent on the quality and robustness of the underlying network infrastructure. When deploying an enterprise network, it is crucial to implement sound network design principles to guarantee optimal performance, reliability, and scalability.

Various aspects of enterprise network design work together to achieve high levels of network performance. This article focuses specifically on quality of service (QoS) and some best practices associated with it.

Advances in VoIP reliability

Posted by Daniel Noworatzky on Jun 29, 2022 10:50:00 AM

In the past, VoIP was considered a low-quality, undependable voice service delivered over an unreliable internet connection. Since then, the technology has improved dramatically, as have the methods and connections used to deliver it. VoIP now enjoys the same levels of availability and robustness as traditional telephony did at its peak.

Even so, the stigma of low quality and low dependability has followed VoIP to this day. In this article, we attempt to understand why this is the case and provide a realistic picture of the phenomenal reliability that VoIP can achieve today.

Using wireless bridging to obtain internet connectivity

Posted by Daniel Noworatzky on Nov 10, 2021 10:47:00 AM

A WAN connection using wireless technology is among the simplest and fastest ways to connect a business to the internet. However, with so many technologies out there, and so many network design and architectural options to deploy, this simple solution can quickly take on a very complex form.

In this article, we hope to simplify the task of sorting through the various choices, allowing you to take advantage of quick, efficient, and often economical wireless options.

How to use SNMP to monitor your VoIP network

Posted by Daniel Noworatzky on Mar 4, 2020 10:47:00 AM

Wouldn’t it be great to have superhero X-ray vision that allows you to understand, in a single glance, what is going on with the voice traffic on your network? In fact, it is possible to do so using the Simple Network Management Protocol (SNMP). In this article, we take a look at this protocol and highlight the special features it has up its sleeve to help you with your VoIP monitoring needs.

How to optimize your Wi-Fi network for VoIP

Posted by Daniel Noworatzky on Sep 11, 2019 10:47:00 AM

Many administrators resist implementing VoIP over Wi-Fi, often citing security and quality concerns. The truth is that if implemented correctly, voice can be safely and reliably deployed on a wireless network. This article examines some best practices for optimizing voice over Wi-Fi (VoWi-Fi).

Quality of service must-haves for converged networks

Posted by Daniel Noworatzky on Nov 7, 2018 10:49:00 AM

IP Telephony features are not always “plug-and-play.” Rather, they must be configured to function properly. This is equally true when dealing with quality of service (QoS) on a network that transmits both data and voice (i.e., a converged network).

Companies commonly find that when they install their VoIP system on a preexisting data network, it works great at first. Days or weeks later, however, users complain of poor voice quality and intermittent disconnections. The network has not changed, so what’s going on?

In this article, we’ll see why QoS is a fundamental part of your network design for voice, and examine five configurations that should always be employed to achieve high-quality voice on a converged network.
