For a safe new year, you need more than a firewall

The beginning of a new year is a time when many business managers reflect on learnings from the previous year and begin working on their goals for the current year. Business continuity and data security are, of course, top priorities and securing the network is a vital part of this. 

For network professionals, there is no word more fearsome than “breach.” A security breakdown can mean lost data, stolen secrets, expensive lawsuits, and more. According to IBM, the average cost of a data breach is now US$4 million. This is why nearly every organization that knows what's good for it now invests in antivirus, data loss prevention (DLP), and of course, firewalls.

These days, however, we need to protect more than just data. Enterprise communications have grown into a multi-billion dollar market, particularly due to the widespread adoption of VoIP and unified communications (UC) services. This presents a new challenge that firms will have to face in order to gain a winning edge: voice security. IP phone services present a whole new attack area to potential hackers, a frontier that firewalls simply cannot protect by themselves. The essence of this challenge lies in the fact that we're talking about two entirely different types of information transmission that, in turn, require different security solutions.

How networks affect sound quality

By Stefan Eriksson, Marketing and Communications Manager of Konftel

Remote meetings with poor quality audio are often exhausting. Misunderstandings become more likely because it’s difficult to hear nuances and other subtleties in conversation. So you want to aim for the best sound quality possible during teleconferences. The following is a quick explanation of different technical requirements for audio quality.

  • A purely mobile solution gives you great flexibility and mobility, but sometimes at the expense of sound quality. Many mobile operators now offer HD Voice in their networks, which delivers HD audio if the phone supports the technology.
  • Traditional analog telephony delivers an acceptable sound quality, but with limitations in frequency range. Sometimes known as telephone quality or narrowband.
  • VoIP, i.e., digital telephony via the data network (voice over IP), allows for extended frequency range, but with some compression. IP makes it possible to achieve superior audio quality, also called HD audio or wideband.
  • Remember that all local networks and accessories, e.g. Wi-Fi, DECT (wireless telephony) or Bluetooth®, affect the transmission capacity and can have an adverse impact on the sound quality.
  • All of Konftel’s phones and conference units offer HD audio in contexts where PBXs and networks support it.

How micro-enterprises can benefit from VoIP

Posted by Daniel Noworatzky on Nov 23, 2016 10:44:00 AM

About 90% of businesses in the United States have fewer than 20 employees, according to the Small Business & Entrepreneurship Council. In the past, companies of this size often couldn’t benefit from PBX functionality like IVR (interactive voice response), hunt groups, hold music, and so forth, because of the high cost of installing and maintaining a PBX.

But today, things are different. Thanks to hosted VoIP service, micro-enterprises can have a phone system with even more functionality than a legacy PBX, even if they only have one user! All they need is a broadband Internet connection. With VoIP, micro-businesses can be more efficient and enjoy the same functionality that big corporations have relied on for decades.

Here we look at how a micro-enterprise can get started with VoIP and some of the benefits it can reap as a result.

Achieve high availability without high cost!

Posted by Daniel Noworatzky on Oct 12, 2016 3:44:00 PM

Ensuring business continuity in case of unexpected service loss is an essential component of any IP telephone system. In a previous blog post we mentioned various failover mechanisms that can be deployed to address different scenarios. Here, we’ll take a closer look at two in particular: backup SIP trunk or ITSP, and failover servers. You may be surprised to discover how easy and affordable they are to set up – especially when compared with the costly alternative of service interruption.

Five reasons you should add an SBC to your IP network

Posted by Daniel Noworatzky on Aug 31, 2016 3:48:00 PM

Despite their limitations, we consider session border controllers (SBCs) to be a best practice in most enterprise contexts because of the improved security, control and overall VoIP system functionality they lend.

So what exactly are SBCs and why do you need one?
