A 2-line phone system, also called a multi-line phone system, is a separate phone line that can be used for business functions such as faxing, remote voicemail, an Internet connection, or to provide a second extension for your business. A 2 line phone system is actually two separate lines that provide two different phone numbers. A 2 line phone system is a cost-efficient way for home-based employees or outside contractors to maintain business communications separate from their home — or personal — phone number and line.
