TeleDynamics Think Tank

Are you hearing both sides?

The very technology that makes VoIP so efficient can also indirectly cause one-way audio issues.

VoIP stands for Voice over Internet Protocol (VoIP), indicating that the communication travels over the internet in little packets using RTP (Real-Time Transport Protocol). Since the packets are traveling through the internet, they must pass through firewalls and network address translation (NAT). Due to the tricky nature of firewalls, a common complaint of customers and installers alike is that either the caller or callee cannot hear the other party. Although this is a common inquiry and topic for support tickets, it is also rather easy to fix.

A useful yet vastly underused functionality of SIP is what is known as presence technology. According to Salesforce, 86% of executives surveyed blamed lack of collaboration or ineffective communication for workplace failures. This is where presence can help.

When providing services for your customers, it’s all about convenience. Imagine a customer trying to find out some information about your service from your website. Her question is very specific and can’t be answered by the FAQs you have on the site. She spots a button on the bottom right of the screen that says “Can’t find what you’re looking for? Talk to a rep now!” She clicks it and is immediately connected via voice to a customer representative and gets her question answered on the spot. Now that’s service!

This is just one of the functionalities that Web Real-Time Communications (WebRTC) provides. A survey conducted by The SIP School found that 88% of professionals have either never heard of WebRTC or only have a cursory understanding of it. Here we present a few facts that will help you better understand how it can benefit your business.

Last week, we touched on some of the technological advances that have allowed VoIP telephony to surpass the PSTN in both quality and reliability.

Yet, even though VoIP has been around for two decades, there are still some misconceptions about what it really is. A lot of people think of VoIP as a technology that allows placing phone calls over the internet. Although this is true, such a narrow definition encompasses only a fraction of the functionality of VoIP.

The unfortunate consequence of this misperception is that VoIP is often associated with low quality and best-effort services that offer low cost or free voice calls over the internet. Those familiar with these services have experienced the frequent disconnects, jitter and stuttering on the line characteristic of this type of service. As a result, VoIP has erroneously been associated with an unreliable user experience.

The truth is, VoIP is much more (and better) than just voice over the internet.

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.

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.
