How to choose a Grandstream SIP phone - in general and in particular?
I work as an engineer at Factor Group , a Grandstream distributor, and participate in pre-sale consultations for various projects. Our clients are not only advanced companies, but also beginners. Therefore, I often talk not only about the lines of Grandstream devices, but also about some basic principles of SIP telephony. And the result of my consultations and my support was this article. I tried to tell both general information and interesting details. I hope the information will be interesting - this is my first experience writing articles.
So, if you decide to switch to SIP-telephony, or want to replace a failed or outdated device with a new one, then you will certainly need IP-phones. This article is written to help you understand the whole range of Grandstream Networks phone lines and choose the best device for yourself or your employees.
Grandstream has 6 categories of IP phones - Basic, Mid-Range, High-End, Premium, DECT and Wi-Fi phones. In this article I will analyze three categories of IP phones - Basic, Mid-Range and High-End. They differ in price range, appearance and, of course, functionality. Phones of the High-End category, for example, have the greatest functionality, have a presentable appearance, but they also have a corresponding price range. But we will go in order and consider each category separately.
Basic IP Phones
Figure 1. Basic IP Phones
The GXP1600 Series of IP Phones is designed specifically for small and medium-sized businesses, as well as for home users. These simple devices have a friendly interface, support for all the basic functions of IP telephony, as well as maximum ease of use.
This category of phones consists of six models: GXP1610, GXP1615, GXP1620, GXP1625, GXP1628, GXP1630.
Figure 2. GXP1610 / GXP1615
GXP1610 and GXP1615 phones differ from each other only in that the GXP1615 has PoE (Power-over-Ethernet) technology support, which allows powering the device from a network cable, in addition to the power supply. Compared to other devices of the categories we are considering, only these phones have no backlight and no support for HD Audio.
These models support one SIP account and two lines, which will allow them to assign one extension number and process two calls simultaneously. They also support three-way audio conferencing and have dual 10 / 100Mbps network interface (LAN and PC). Using the PC connector is very convenient if only one computer is connected to the local network at the employee’s workplace. When you connect a computer with a network cable to the PC phone port, the phone will act as a switch and an additional port on the main switch will not be required. Absolutely all phones of the Basic, Mid-Range, High-End and Premium categories support this mode.
Another feature that is available on all Grandstream desk phones is the RJ9 headset port. But you need to make a small reservation. The manufacturer itself has tested many types of headsets. Their support is guaranteed and you can study this list for phones of the 16th series here , and for all other phones here .
Figure 3. GXP1620 / GXP1625 The
GXP1620 and GXP1625 phones also differ only in that the GXP1625 has PoE technology support. And I note that of all the lines of phones, only two models - GXP1610 and GXP1620 do not have support for this technology.
The GXP1620 and GXP1625 models support two SIP accounts and two lines, have a backlight, HD Audio support, three-way audio conferencing and dual 10 / 100Mbps network interface.
Figure 4. GXP1628
The GXP1628 model is similar to the GXP1625 model except for eight MPK keys (Multi-Purpose Keys) with the BLF function, which allows you to monitor the state of employment of telephones of your colleagues. Multi-tasking MPK keys allow you to perform the most common actions with one touch. As a rule, these keys are assigned a quick call to the most frequently dialed subscribers, or a call transfer, which eliminates the need to store telephone numbers in memory and does not waste time searching for them in the phone book. The presence of shortcut keys greatly facilitates the daily work with the IP-phone, especially for employees making many phone calls. Also, this model differs from the GXP1625 by the presence of a gigabit network port.
Figure 5. GXP1630
And the GXP1630 model is similar to the GXP1628, but also has its own differences. GXP1630 has support for three SIP accounts, three lines and can organize a four-way audio conference.
For convenience, I will give a general comparison table for the category of Basic IP phones:
Table 1. Comparison of Basic IP phones
|Parameter / Model||GXP1610 / GXP1615||GXP1625 / GXP1620||Gxp1628||Gxp1630|
|PoE Support||No Yes||No Yes||Yes||Yes|
|Number of lines||2||2||2||3|
|Number of SIP Accounts||1||2||2||3|
|Network interfaces||10/100 Mbps||10/100 Mbps||10/100/1000 |
Mid-Range IP Phones
Figure 6. Mid-Range IP Phones The
GXP1700 Series IP Phones are designed for small and medium businesses. These stylish devices have all the necessary capabilities that are in demand in growing organizations. At the same time, the devices of the GXP1700 series have a reasonable price, which reduces the burden on the budget of companies. In addition to functionality and price, the phones have an excellent design and thoughtful ergonomics, so working with them is a pleasure.
This category of phones consists of four phones: GXP1760, GXP1760w, GXP1780 and GXP1782. I’ll note right away that the GXP1760w phone has a built-in dual-band Wi-Fi module, so it belongs to Wi-Fi phones and we will look at it in more detail in another article.
Figure 7. GXP1760 Let's
start with the GXP1760. This model has a two-color LCD screen with backlight, support for three SIP-accounts, six lines and the ability to organize a five-way audio conference. Six keys on the sides of the display and the ability to switch four pages on the home screen with the left and right navigation keys give a total of 24 virtual BLF keys
Figure 8. BLF keys
For personalization options, the GXP1760 supports various ringtones, as well as Web applications such as weather forecasts. The GXP1760 is also equipped with a Kensington Security Slot to prevent it from being stolen from public places such as checkpoints, hotel halls, reception areas and others. Two 10/100 Mbit / s ports are used to connect to the network, the device can be configured via the Web-interface, as well as using various auto-tuning technologies:
- Auto Provisioning when using IP-PBX from Grandstream;
- self-loading .xml configuration files through DHCP option 66;
- support for auto-tuning services 3CX and Broadsoft;
- Grandstream Automated Provisioning System (GAPS) is an automated system that allows IT administrators and telecom operators to directly and securely control device provisioning and optimizes the massive deployment of Grandstream products from a central control panel.
Figure 9. GXP1780 / 1782
The GXP1780 differs from the GXP1760 in that it has support for four SIP accounts and eight lines. This model has eight physical BLF keys, and the ability to turn over the home screen gives 32 virtual BLF keys. The GXP1782 differs from the GXP1780 only in a gigabit network interface.
In addition to the RJ9 port for connecting a headset, the 1700 series phones have a separate EHS port for external EHS adapters.
Figure 10. Port for EHS adapters
For convenience, I will give a general comparison table for the category of Mid-Range IP phones:
Table 2. Comparison of Mid-Range IP phones
|Parameter / Model||Gxp1760||Gxp1780||Gxp1782|
|Number of lines||6||8||8|
|Number of SIP Accounts||3||4||4|
|BLF keys (physical / virtual)||6/24||8/32||8/32|
|Network interfaces||10 / 100Mbps||10 / 100Mbps||10/100 / 1000Mbps|
High-End IP Phones
Figure 11. High-End IP Phones The
high - quality GXP2100 Series IP Phones are designed for users who need advanced telephony features. These devices have rich functionality. Features such as a high-quality HD speaker, a clear color display, the ability to customize your desktop wallpaper, various BLF key combinations and support for additional expansion panels, built-in Bluetooth, PoE, gigabit network ports on all models - all these are the distinguishing characteristics of advanced IP phones of the series GXP2100.
This category includes 5 phone models: GXP2130, GXP2135, GXP2140, GXP2160 and GXP2170.
Figure 12. GXP2130
The first model in this line is the GXP2130. This phone has a 2.8-inch color LCD with a resolution of 320x240 pixels. It supports three lines and three SIP accounts and provides the ability to arrange a four-way audio conference. A distinctive feature of this phone is the presence of eight MPK keys with BLF function. However, by analogy with Mid-Range phones, High-End devices also have the ability to configure the BLF virtual keys. The presence of three physical keys to the left of the display and four pages for scrolling give a total of 12 virtual BLF keys in addition to eight MPK keys.
Figure 13. BLF keys
I will tell you separately why Bluetooth is needed in phones of this series. Support for Bluetooth technology is present in all High-End phones of the 21XX series and significantly expands the capabilities of the phone. To begin with, you can connect an external Bluetooth-headset, which will save you from “binding” to the phone, as happens when using wired headsets. In addition, it is possible to connect a mobile phone to the IP-phone.
Figure 14. Mobile phone account
With this scheme, the IP phone itself will act as the headset for the cell phone. When connected, the “account” of the mobile phone will automatically appear on the IP phone, and it will be possible to make calls from the IP phone without using a mobile phone, this is the so-called Hands-free mode. Incoming calls to a mobile phone will also be displayed on the IP phone. And if you need to call a contact that already exists on your mobile phone, you can help the ability to synchronize contacts between IP-phone and mobile phone via Bluetooth.
Figure 15. GXP2135
The next model is the GXP2135. It differs from the previous one in the number of lines, SIP accounts, the presence of a larger number of BLF keys and the absence of MPK keys. This phone supports eight lines, and four SIP accounts. There are eight BLF keys on this phone, and the ability to scroll the home screen increases the number of these keys to 32.
Figure 16. GXP2140
The last three models of the GXP2140, GXP2160 and GXP2170 phones have an enlarged screen. Its dimensions: 4.3 inches and a resolution of 480x272 pixels. The GXP2140 supports four lines, four SIP accounts and can organize a five-way audio conference. Four keys to the left of the screen with the BLF function, by analogy with other models, make it possible to create 16 virtual BLF keys.
A distinctive feature of this model is that you can connect the GXP2200EXT expansion panel to it.
Figure 17. GXP2200EXT
Figure 18. GXP2140 and GXP2200EXT The
GXP2200EXT is an optional keypad with a graphical LCD display that provides additional functionality, flexibility, and scalability to the Grandstream GXP2140, GXP2170, and GXV3240 IP telephones. The module has a large 128 x 384 graphic LCD display and 20 programmable keys (each key can glow in two colors), and the ability to switch the screen gives 40 keys on one panel. In total, up to four GXP2200EXT panels can be connected to Grandstream IP phones. Thus, up to 160 shortcut keys are supported when using 4 expansion modules. The expansion module is connected, receives power and is controlled by the phone, providing additional functionality immediately after connecting the module.
Figure 19. GXP2160
Our next phone is the GXP2160. It supports six lines, six SIP accounts and the organization of a five-way audio conference. The six BLF keys to the left of the screen and the ability to scroll the home screen add up to 24 virtual BLF keys. This phone does not support the connection of an additional extension panel, but it has a similar integrated panel. It has 24 MPK keys with a BLF function.
Figure 20. GXP2170
Our top-end Grandstream GXP2170 IP phone supports 12 lines, 6 independent SIP accounts and is able to organize a five-way audio conference. Thanks to the 12 keys with the BLF function on the sides of the screen and the ability to scroll, you can configure up to 48 virtual BLF keys. This phone also supports the connection of an additional extension panel GXP2200EXT, which makes it perfect for employees who actively use telephone communications in their work.
And so that you can clearly see the differences between the phones of this series, I will again give a comparison table:
Table 3. Comparison of High-End IP Phones
