Manual of product GXP2120
Editorial note
The Grandstream GXP2120 stands out for its optimal audio quality, made possible by advanced codecs such as G.722, G.723.1, G.726, and iLBC. These features ensure clear and immersive communication, ideal for professional environments. Additionally, the call management features, including hold, call forwarding, and the ability to conference call, facilitate effective and smooth communication. Its modern and sleek black design, combined with an ergonomic 45-key keyboard, offers a pleasant user experience. However, the lack of a touchscreen may make interaction less intuitive compared to other competing models. Furthermore, the limited number of Ethernet ports (only one) and the absence of wireless connectivity, such as Bluetooth or Wi-Fi, may restrict usage flexibility. In terms of value for money, the GXP2120 positions itself satisfactorily, although some users may be discouraged by the relatively low screen resolution of 320 x 160 pixels and the lack of an extension module for increased customization. Finally, while the user manual provides useful information, more comprehensive online documentation could enhance the support experience. Overall, the Grandstream GXP2120 is a good choice for those looking for a high-performance IP phone, but it may not suit everyone due to its limitations in connectivity and interaction.Score details
