No additional telephone lines or features are needed to use RingCentral. The unified messaging provided by RingCentral is a completely stand-alone service. To answer incoming calls, you will need a phone with dial tone—that could be a cell phone, your home phone, an office phone or any other existing line. You can also answer incoming calls through your PC with Softphone, a free RingCentral download. RingCentral receives voicemail and faxes 24x7 and saves them to your online account. You can retrieve and listen to these messages directly through your computer speakers. No additional local or long distance telephone features or hardware are required for RingCentral to function.
