Cisco 7931G is considered as one of the best multifunctional phones with 24 phone line keys. Due to high number of keys (24 line keys with backlight and 4 interactive menu keys with all features and possibilities of the phone), this model can work independently from CP7915 and CP7916 panels, what makes the organization of the office cheaper.
