Yes. With the RingCentral MVP VoIP service, you can manage all of your inbound faxes by internet fax (which we will convert to PDF and then send to your email inbox). But you can also use your traditional fax machine to send faxes with VoIP using your RingCentral service. To do so, you just need to connect your fax machine to a VoIP ATA and then connect the ATA to your internet router.
Note: Sending faxes the traditional way using your RingCentral service will require you to buy one RingCentral MVP line for the fax machine itself.
