Manual of product 3911
Editorial note
The Cisco 3911 stands out for its exceptional audio quality, thanks to optimized voice codecs such as G.711 and G.729, which ensure clear and crisp communications. Its ergonomic design with a 12-key keypad makes it easy to handle and enhances the user experience. Additionally, advanced features like call waiting, call forwarding, and the ability to conference call enrich the communication management experience, making this device suitable for professional environments. However, the phone has some limitations. The lack of a touchscreen and speed dial function may restrict interaction and slow down access to favorite contacts. Furthermore, the absence of Intercom functionality could pose issues in environments requiring quick communication between different stations. Although the audio quality is good, the lack of active noise cancellation may affect performance in noisy settings. Finally, weighing 505 g, the Cisco 3911 may feel relatively heavy, making it less convenient to move around. In terms of value for money, the Cisco 3911 offers reliable network connectivity and compatibility with Power over Ethernet (PoE), making it appealing, although it lacks some features found in newer models. Overall, the Cisco 3911 is a solid choice for those seeking a functional and efficient desk phone, despite a few drawbacks to consider.Score details
