Onsite digital fax servers typically call for onsite fax telephony—phone lines, fax boards, etc. While some organizations appreciate having full control over all aspects of the faxing process, others are looking to save their IT department time and resources. Hybrid fax solutions offer the control of an onsite server deployment with the reduced hassle and high availability of cloud telephony. Frequently they are seen as an upgrade to an existing on-premises install, allowing organizations to continue to derive value from past investments.
