For many years Sangoma has been well known for making PCI cards that can be used inside IP PBX’s but had never made the crossover to being an IP PBX manufacturer. Their first foray into this market came in June 2012 when they released the Lync Express. Now, with the release of the new Sangoma PBXcelerate, they’re making further inroads into the PBX appliance manufacturer market and their first to the SIP and open source IP-PBX marketplace.

Sangoma PBXcelerate

What Is It?

The Sangoma PBXcelerate is a highly customizable IP PBX appliance designed for use in small to medium sized offices as well as branch offices.

The first of the customizable features of the PBXcelerate is the PBX software that is loaded or lack thereof. This Sangoma …

Grandstream GXP2130 First LookI’m starting to wonder if the off switch at the Grandstream new phone model assembly line is broken because today they announced another new VoIP phone with even more on the way. The newest model off the conveyor belt is the Grandstream GXP2130.

What is it?

Of the latest enterprise grade VoIP phones in the GXP series Grandstream GXP2130 is the entry level phone; although, entry doesn’t mean it is a stripped down phone. Quite to the contrary the GXP2130 has many of the same features as the GXP2140 and GXP2160 that were released at the end of last year. These similar features include a TFT Color LCD Display, dual gigabit RJ45 ports, support for PoE and EHS support with Plantronics headsets.

What separates …

Grandstream GXP2140 and Grandstream GXP2160Earlier this year I posted about the amount of changes Grandstream phones had gone through over the course of two years. At the time of writing the post 5 phone models had been discontinued and 10 new models had been released. Now here we are 10 months later and we can add one more to the discontinued column, Grandstream GXP2124, and add two to the new model column, Grandstream GXP2140 and Grandstream GXP2160.


The GXP2140 and GXP2160 are the two latest enterprise VoIP phones from Grandstream and are the replacements for the Grandstream GXP2124. Within the GXP family of phones they will be the higher end phones above the GXP2120 but don’t have as many features as the Android based GXP2200. Additionally …

Yealink SIP-T19P and Yealink SIP-T21PEarlier this year Yealink broke their mold, aesthetically speaking, when they released three new VoIP phones. These new phones featured a new design that looked quite different from the models they have been producing for the last couple of years. This doesn’t mean that they’ve completely changed their ways and to see the proof of this you only need to look at their two latest entry level phones, the Yealink SIP-T19P and Yealink SIP-T21P.


The SIP-T19P and SIP-T21P are two new entry level VoIP phones from Yealink. As previously eluded to these two models follow the design of the existing T2X and T1X phones. So much so that out of the gate we had a small game at the VoIP Supply …

This is my desk. There are many like it, but this one is mine. . .and boy is it a bit of a mess.

I am a Headset Hoarder

So why am I reciting a variation of the Rifleman’s Creed and showing a cluttered photo of my desk?

Partially to publicly shame myself into taking some action and clean it up but also to talk about a small problem I have that is shown in the photo, that I can now admit to openly and take steps to conquer.

I am not talking about the layer of dust over everything that rivals a mid-winter snow storm, the fact it is one of the last Fridays in the summer and I’m at work, or the two phones on my desk but, …

Before I go any further I have to be honest, when the touchscreen VoIP phones first came out I was somewhat skeptical. Sure it was cool but it seemed a little unnecessary and, dare I say it excessive, to have a touchscreen on a desk phone. But in the years since my opinion has shifted and now I want a touchscreen VoIP phone on my desk.

I think maybe this ‘want’ is just an extension of the fact that a lot of the things I own and use touchscreen. My cell phone is touchscreen. My laptop/tablet is touchscreen. While my displays for my desktop computers at work and home aren’t I’ve found myself touching the screen only to be disappointed when nothing happens, so: In …

Lync LogoOver the last couple years Microsoft Lync, formerly Microsoft Office Communicator, has been gaining a larger share of both the enterprise and the SOHO/SMB unified communication market. If you ask a room of people in the know about UC platforms what Lync 2013 is you’ll most likely get a group response reminiscent of students repeating a lesson back to a teacher that “Lync is a unified communications platform that provides a single client experience for presence, instant messaging, voice, video and a great meeting experience” or something along those lines.

Ask a follow up question what the difference between a device that is Optimized for Lync compared to one that is Compatible with Lync and you’re more than likely to hear the sound of few …

In May Yealink announced a new series of VoIP Phones that marked a change from their current line of SIP-T2 and SIP-T3 VoIP phones. To get a better understanding of the decision to release these new models and how Yealink seems them fitting in the current VoIP phone market I talked with Cheng Zhang, Marketing Manager at Yealink.

Yealink T4 VoIP PhonesVoIP Supply: While I am looking forward to learning more about the new Yealink SIP-T4 phone models before we start for those who aren’t familiar with Yealink would you be able to tell me a little about Yealink?

Yealink:Founded in 2001, Yealink is the Global Top5 SIP Phone Supplier and a leading provider of VoIP Phone and IP communication solutions. Yealink focuses on VoIP products characterized …

The phrase “champagne on a beer budget” gets a bad rap in my opinion. When used it seems like there is usually a negative connotation associated with it but I don’t think that should always be the case. Sometimes it could be used to imply that you are getting more for less, which isn’t a bad thing. One example of how you could use the phrase in a positive manor is to describe the new Grandstream UCM6100 series of IP PBXs; where you get many of the features of an expensive enterprise grade IP PBX without the price tag or champagne on a beer budget.


The Grandstream UCM6100 is a series of 4 new IP PBXs that have been targeted at …

With Microsoft WPC 2013 in full swing this week in Houston, Texas it wouldn’t be surprising to see quite a few Lync product announcements coming out and Polycom has duly obliged. Today Polycom announced the release of two new Lync video conferencing units and Lync qualification for their VVX Business Media phones.

According to the press release the new Polycom CX5500 and Polycom CX5100 are “the industry’s first 360-degree, panoramic 1080p HD video collaboration solutions custom-built for Microsoft Lync 2013.” Additionally each model supports 30 frames per second, Polycom HD Voice and USB connectivity allowing them to be connected to a computer. The main difference between the two models so far seems to be the ability of the CX5500 to double as a SIP …
