Grandstream’s 17xx IP phones are both functional and cost-effective

Posted by Daniel Noworatzky on Jun 28, 2017 3:48:00 PM

The family of endpoints includes the GXP1760, GXP1780 and GXP1782 models

 


Telecommunications infrastructure can be one of the biggest costs for a small- to medium-sized company, so it’s critical to find a solution that strikes the right balance between value and cost, while at the same time ensuring scalability so the system can grow along with the business.

IP phones often comprise the bulk of the cost of a business telephone system, so choosing the right endpoints is an important part of the functionality-cost ratio. Developed specifically with growing businesses in mind, Grandstream’s mid-range GXP17xx series IP phones achieve this balance remarkably well.

How to troubleshoot one-way and no-way audio on VoIP calls

Posted by Daniel Noworatzky on Jan 25, 2017 3:38:00 PM

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.

How Android converts IP phones to productivity centers

Posted by Daniel Noworatzky on Jan 18, 2017 3:40:00 PM

 

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.

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.

A simple process for transitioning to VoIP

Posted by Daniel Noworatzky on Nov 16, 2016 3:40:00 PM

 

Replacing a legacy PBX that a company has used for years with an IP PBX can be intimidating, and understandably so. That’s why we recommend a transition method that allows the new technology to be gradually introduced over time. This not only ensures business continuity but also gives the associates plenty of time to adjust to the new equipment.
