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.

QoS for VoIP networks: IntServ versus DiffServ

Posted by Daniel Noworatzky on Oct 17, 2018 10:48:00 AM

Your customer using a legacy phone system decides to switch to voice over internet protocol (VoIP). They install an IP PBX and buy some IP phones. Great, they’re all set, right? Wrong. Without configuring their data network for quality of service (QoS), they will experience a severe deterioration in voice quality and may regret making the decision to switch. Yes, the IP PBX and the IP endpoints will already be configured for QoS. But what about other parts of the network like the pre-existing routers, switches and firewall? All it takes is one missing link for the whole system to be compromised.

QoS is a big topic. In this article, we’ll look at two main approaches to QoS: IntServ and DiffServ, their strengths and limitations, and when to use which one.

Customizing a VoIP deployment for your multisite customer

Posted by Daniel Noworatzky on Oct 10, 2018 10:48:00 AM

 

Over the past few weeks we’ve looked at different ways to structure multisite VoIP deployments. The truth is, each business is unique and sometimes a customized architecture is needed. In this article we look at a hybrid solution. A hybrid call processing deployment allows you to craft a solution that is perfectly tailored to a specific customer’s needs.

How to set up centralized call processing in a multisite enterprise

Posted by Daniel Noworatzky on Sep 26, 2018 3:53:00 PM

Enterprises with multiple sites have a variety of options when it comes to their IP telephony infrastructure. Which setup will best meet their needs depends on the answers to questions such as:

  • Where should the call processing take place?
  • Where should calls to the PSTN exit the network?
  • Where should incoming calls connect to the corporate network?

These decisions depend on the nature of the underlying network infrastructure that will carry the IP telephony services, as well as other considerations such as the location of the remote sites, the dial plan, and cost.

In this article, we discuss the centralized call processing model and how to avoid common complications with its deployment.

SD-WAN is good for single-site companies, too

Posted by Daniel Noworatzky on May 9, 2018 3:48:00 PM

...Especially if they have lousy internet service

Because of its name, most people think of SD-WAN as being relevant only for companies with multiple sites. But SD-WAN can do wonders for many types of companies – even a single-site business located in a remote area with an unreliable internet connection. If you work with a company that fits this description, SD-WAN can resolve a lot of their VoIP issues.

WAN connections and the SIP trunk: What’s the connection?

Posted by Daniel Noworatzky on Jan 17, 2018 3:54:00 PM

How you connect to the internet will impact your VoIP phone system

Because SIP trunks leverage the WAN technology used to connect to the internet, it is imperative to understand how the choice of WAN technology will impact the functionality of the SIP trunk. There are different ways to connect to the internet, and each has implications for voice traffic.

In this article, we discuss the main considerations to take into account when choosing between MPLS, metro Ethernet, LTE and SD-WAN.

EdgeMarc SBCs that scale with growing businesses

Posted by Daniel Noworatzky on Oct 26, 2017 10:00:00 AM

Review of the EdgeMarc 2900a and 2900e Enterprise Session Border Controllers

Edgewater Networks has added to its line of enterprise session border controllers (eSBCs) with its EdgeMarc 2900a and 2900e models. These are designed to enable enterprises and service providers to future-proof their SIP trunking and Unified Communications (UC) deployments. With built-in mechanisms for both QoS and security, they provide intelligent mechanisms allowing for both hosted PBX services as well as SIP trunking applications.

They have several features that differ from other EdgeMarc SBCs.
