Note, however, that this article is really designed to be read through in its entirety as the capabilities of businesses benefit from evaluating all three areas of the phone before deciding which will best suit their needs.
Grandstream’s solutions are used by companies in more than 150 countries and include IP telephones, headsets, Wi-Fi management solutions and scalable unified communications offerings.
This review focuses on three specific areas of IP phones offered by Grandstream: the GFK, GXP, and GXV areas. All devices offered in these areas offer the quality and reliability for which Grandstream has become known over the past two decades. However, the different features are more suitable for some companies than for others.
However, companies that opt for one of the Grandstream handsets listed below are sure to come across handsets that offer excellent call quality and are particularly well suited for group conferences. Whether your business needs video calling capabilities, Bluetooth connectivity, or any number of other VoIP features, Grandstream needs to have a device that suits you.
Grandstream IP Phone GRP range
There are two different sets of equipment within the GRP area of Grandstream. First, the Essential IP Phone line is designed to be mass provisioned and easy to manage. There are four devices in this range that aim to deliver next-generation features at an affordable price.
The standout phone here is the GRP2604 – a three-line model that features a sleek design and some of the important features that modern businesses have come to expect from their IP phone. This includes five-way voice conferencing, integrated power supply via Ethernet, full HD audio on both the speaker and the handset, and support for multiple languages.
Enterprises will also be pleased to see that the GRP series offers carrier-level security features including secure boot, dual firmware images and encrypted data storage. The GRP2604 is also supported by Grandsteam’s cloud-based device management system, which provides users with a centralized platform to configure and manage their Grandstream endpoints.
The GFK series also includes five mid-range IP telephones with carrier quality, which are equipped with a more comprehensive range of functions. These handsets are designed for corporate customers and other high volume businesses. The GRP2612 starts at the lower end and has 16 multi-purpose virtual buttons, a full color LCD screen and a host of other functions. The inclusion of a replaceable faceplate is also a nice touch and gives businesses an additional branding option in the workplace.
The GRP2613 is primarily committed to efficiency. The handset has three SIP accounts, six multi-purpose buttons, HD audio with support for all common codecs and a color LCD display. The GRP2613 is designed for smaller businesses that can’t afford to waste time on inefficient equipment. Setup is also straightforward. All users need to do is unpack and assemble the phone, which includes the handset, an ethernet cable, and a power adapter. The easy-to-follow instructions make configuring your Grandstream GRP2613 device on your network as easy as possible.
Those looking for a premium experience should try the GRP2614. This model outperforms some of the other fiberglass devices in terms of call quality – especially when using the speakerphone. The inclusion of 40 multi-purpose virtual buttons as well as dual LED screens is sure to be welcomed by high volume users too, especially since the bottom LED is customizable so that users can configure it for quick access to frequently dialed numbers, for example.
The GRP series is rounded off by the GRP2615 and GRP2616 models. These high-end units share the same sleek design as the other Grandstream models, but also have full color LCD screens and the option to add a larger number of SIP accounts. For businesses that need their VoIP phones to see the part, these are probably the fiberglass models that will appeal the most.
Grandstream IP Phone GXP series
Grandstream’s GXP series of phones are designed for users who make frequent calls and may need access to advanced features. The company offers basic, mid-range, and high-end IP phones that offer a variety of interactive communication features depending on the needs of the user.
The basic IP phones range from the GXP1610 / 15, which offers optimized service and only one SIP account, to the GXP1630, which supports three SIP accounts. In between there is the Grandstream GXP1625 IP Phone, which promises both a full HD sound quality and a backlit graphic display with 132 × 48. The three-way audio conferencing option should also help employees collaborate wherever they are.
Looking at the mid-range GXP phones available, Grandstream envisions that these phones will be ideal for businesses that are seeing rapid growth as they offer the flexibility that scale-ups require. Two handsets are available here. The first, the GXP1760W, is ideal for businesses handling moderate call volume. It offers dual-band WiFi for easy integration into wireless networks and an elegant design. The GXP offers even more scalability with its four SIP accounts and its eight two-color line buttons.
However, businesses that need access to more advanced features should check out the high-end offerings in the GXP range. For example, the GXP2130 v2 has a 2.8-inch color LCD screen, four programmable XML softkeys, and the option to use three SIP accounts. Additional functions such as integrated Bluetooth, HD audio and two gigabit network connections are also included.
Businesses will also find that the GXP2130 v2 comes at a very affordable price, with the rare occurrence of a color screen IP phone being available at that price. Regarding the cons, some users have complained that this particular model feels a little small and is not as comfortable in the hand. Others have argued that the graphic symbols used to identify the functionality of each key are not always the most intuitive.
If employees are not satisfied with the GXP2130 v2, they can try other models. For example, the GXP2135 offers fast and powerful ease of use – the kind users need to manage medium to high volume calls. The handset has 32 digital speed dial buttons, eight physical line buttons and four-way audio conferencing. However, the color LCD screen has been reported to fade over time by a minority of users.
Grandstream IP Phone GXV series
GXV devices clearly stand out from the other VoIP cell phones offered by Grandstream. They run on the Android operating system and offer a kind of hybrid functionality: part VoIP phone, part tablet. The devices, of which there are three, offer all of the video features that could prove essential for businesses in need of a multimedia experience.
The latest but cheapest addition to the product range is the GXV3350 IP video phone, which offers both a cross-platform solution for video collaboration and the functionality of an Android tablet in an all-in-one communication solution. The GXV3350 has a capacitive 5-inch touchscreen (1280 x 720), an HDMI output, two microphones and an adjustable camera. PoE gigabit ports, built-in Wi-Fi connectivity, and Bluetooth support are also included.
The GXV 3370 offers similar features but a slightly larger screen. It also offers flexible SDK support for custom apps. This handset features a 7-inch touchscreen and is fully compatible with almost all major SIP platforms. The GXV3370 will be welcome in most developing workplaces. The three-way 720p video conferencing feature should be particularly useful for businesses involved in remote collaboration.
Finally, the GXV3380 IP Video Phone for Android is the most advanced of the GXV range. This 16-line IP video phone features an 8-inch (1280 x 800) capacitive touchscreen, two megapixel camera, HDMI input / output for content sharing and support for 1080p HD video. Despite its many fancy features, the GXV3380 couldn’t be easier to use. The fact that it runs on the Android operating system means that many users are already familiar with the underlying technology, which makes each learning curve extra gentle.
One of the biggest attractions of the GXV range is the fact that these phones offer access to thousands of Android apps. This could significantly increase the productivity of a company’s employees by giving them quick access to the workplace tools they need without having to bother with another device. The devices of the GXV series are more than just a VoIP telephone. They are powerful business tools that offer capabilities that go well beyond just sending and receiving calls.
Our overall judgment
Grandstream’s VoIP devices really offer something for everyone. For businesses with smaller budgets or less intense VoIP needs, the GFK range may be the best solution – although it should be noted that a small number of customers have reported malfunctions with some of these models.
For businesses that want more flashy VoIP phones, the GXV series offers some really impressive phones. The ability to make calls using the familiar Android operating system is likely to appeal to a number of businesses too – as does the bright, clear screen and crisp audio quality.
Overall, Grandstream’s VoIP phones are a great all-rounder for any office – especially those who have a significant number of conference calls.
