Grandstream GVC3200 star_orange_24 star_orange_24 star_orange_24 star_orange_24 star_orange_24

The following review was conducted in June 2016.

Introduction

The Grandstream GVC3200 is a video conferencing system with support for popular video conferencing protocols and platforms right out of the box. The GVC3200 is a standalone device, but it must be coupled with a speakerphone for full video conferencing functionality. Any USB or bluetooth speakerphone can be used with the GVC3200.

The GVC3200 comes with Grandstream's GAC2500, an Android-based conference phone, so you won't have to go searching for additional parts as soon as you take the device out of the box. But it's up to you if you want to use a different speakerphone or not. This review will focus entirely on the GVC3200, but if you're interested in the GAC2500, check out our review here.

Grandstream GAC2500 star_orange_24 star_orange_24 star_orange_24 star_orange_24 star_orange_24

The following review was conducted in October 2015.

The Grandstream GAC2500 is the company’s first conference phone. It follows in the path of the GXV3275 and GXV3240 as a touchscreen Android device. The smartphone-esque feel makes it sleeker than the conference phones we've become accustomed to, and the inclusion of this sort of interface means that the GAC2500 has already broken new ground, before we even start the review.

Cortelco C62 star_orange_24 star_orange_24 star_orange_24 star_orange_24 star_grey_24

The following review was conducted in October 2015

The Cortelco C62 marks the company's foray into executive IP phones. Unlike the Cortelco C56, a product that pared down its capabilities as much as possible, the C62 takes a slightly different approach by offering features that are common to most mid-range phones (multiple lines, more BLF buttons).

Grandstream GXP1628 star_orange_24 star_orange_24 star_orange_24 star_orange_24 star_grey_24

The following review was conducted in September 2016.

The Grandstream GXP1628 is the most elaborate phone in Grandstream's new line of inexpensive SIP phones. The GXP1628 is shooting for the general use crowd with its respectable feature set and decent HD voice capabilities. Imagine a stellar office phone that prices about $100 less than the Polycom Soundpoint IP 550 —that's what the GXP1628 is looking to offer.

Cortelco C56 star_orange_24 star_orange_24 star_orange_24 star_orange_24 star_grey_24

The following review was conducted in October 2015.

The Cortelco C56 is one of the simplest SIP phones we've ever reviewed. With its easy configuration and its bare bones interface, the C56 is clearly not trying to win the arms race of smartphone-esque UIs and advanced features that some other manufacturers are aiming for.

Grandstream GXP2200 star_orange_24 star_orange_24 star_orange_24 star_orange_24 star_orange_24

The following review was conducted in April 2013.

In our last review of a touchscreen phone from Grandstream, we stated that we were excited about the direction the company was going with their multimedia IP desk phones—with the caveat that the sluggish, resistive touchscreen they included in the design detracted significantly from the user experience. If anything, it underscored the gap in user friendliness between smartphones/tablets and the newer desk phones trying to emulate them. Since the touchscreen was the only way to interact with the phone we were reviewing at the time (Grandstream GXV3175), there was no getting around it, which made even simple tasks like dialing a phone number more frustrating than they needed to be.
