Cloud fax supports sending and receiving faxes without the usual fax machines, phone lines, or on-premises digital fax server software. All fax communications are instead digitized and sent via the Internet Protocol (IP) network to the cloud before routing to the analog fax machines and fax-enabled printers connected to the telephone and IP networks or, indeed, to cloud-based fax recipients. Cloud fax services allow enterprises to avoid on-premises telephony costs related to fax phone lines or IT costs to support the on-premises fax infrastructure.
