The number of lines on a grandstream IP phone determines how many simultaneous calls or extensions can be managed at once, making it a crucial factor for businesses with varying communication needs. For example, a 2-line phone is ideal for small offices or individual users, while a 3-line model supports busier environments or receptionists handling multiple calls. Available options range from 2 lines, as seen in the Grandstream GRP2602P, to 3 lines on models like the Grandstream GRP2603P. This variety ensures users can select a phone that matches their call volume and workflow, with flexible options for growth or specialized roles.
