The upgraded phone line takes the stack of advanced features even higher.

With the T4 series of IP phones, Yealink offers a well-rounded array of sophisticated calling features, state-of-the-art voice quality, easy installation, robust customization options and extensive expandability. Early in December 2016, Yealink released the upgraded T4S models based on the former T4 series in the North America region. The T4S models build on the user experience even more with a number of upgrades.

When most people hear about VoIP, they think of telephony over the internet. Online services that offer extremely-low-cost phone calls or even free calls may come to mind. Although such services do utilize VoIP (voice over internet protocol), IP telephony in a broader sense is technology and architecture that uses VoIP to allow you to create an internal telephone network within your organization that leverages the existing data network infrastructure.

IP telephony operates on converged network, which supports both voice and data. The advantages of this to a business are numerous and are well worth the investment. If you are considering a migration to IP telephony, here we present some information that can help get you on track.

As one of the biggest expenses of any business, telecommunications solutions should be both reliable and cost-effective. One telephony network design aspect that can provide both is the direct connection of the IP phone system to a mobile network.

Here we explore two ways to do this, either of which not only achieves cost savings for the company but also enhances reliability by providing an additional redundant and overflow route.

If you deal with Voice over IP (VoIP), you must have come across this scenario at one time or another: A user complains that when they answer their phone, the caller can’t hear them, even though they can hear the calling party. Or, it may be that neither party can hear the other and there is just silence on the line.

This is the classic case of one-way or no-way audio, where a voice call is successfully completed, but either the voice packets only successfully travel in one direction, or neither end successfully receives voice packets. It may be difficult to understand why this happens, especially since the phone does ring, both physically for the called party and via the ring-back tone for the calling party. It seems counterintuitive that the transmission of voice packets could be unsuccessful if the call was successfully set up.

This is a scenario that comes up a lot on our tech support calls at TeleDynamics. Here we list four of the most common culprits of this issue and suggestions for how to tackle them.

Grandstream and Ubiquiti add excitement to desk phones by leveraging the power of Android OS and a modern interface. By integrating the Android Operating System into the phone, thousands of business productivity applications like Skype, GoToMeeting, Gmail and more can be downloaded onto these phones from the Google Play store.

Advanced apps ranging from Pomodoro Technique Timer to more obvious solutions provided by Google Calendar will make workers in any industry more productive as they perform phone call campaigns and meetings with one device instead of two. The versatility that the Android platform provides is a huge differentiator that separates these phones from a typical IP phone.

Here we look at five SIP endpoints from Grandstream and Ubiquiti that use Android OS.

When it comes to VoIP PBX systems, channel partners need to determine whether an on-premise solution or a cloud-based service is best suited for their customer.

Each solution has its strengths. For the instances in which you determine that an onsite IP PBX is the best option for your customer, we’ve put together these guidelines to help you sell against the hosted solutions offered by your competitors. Here at Yeastar, we work with thousands of channel partners who find themselves in competition with cloud-based VoIP service providers and have identified the most compelling arguments for an on-premise solution. Think of each one as an additional arrow in your sales quiver.

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.

For many businesses, videoconferencing has traditionally been seen as being a pipe dream – something they would love to be able to utilize but cannot because of a variety of factors. But not anymore: the videoconferencing marketplace is currently going through a major transformation.

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.

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.
