4-Line Phones

4-line phones and phone systems help you expand the communication capabilities of your business or workplaces. These multi-line business phone systems let you operate up to four separate phone lines on a single telephone system. That means up to four users can attend to the phone calls at the same time. Therefore, your businesses can use 4-line phone systems to employ separate lines for internal and external communications. In this way, they can have different lines for their customers' calls and office team coworkers.
