A method to efficiently and reliably guarantee delivery of fax documents not residing on the internet being transported through the internet to a non-internet fax receiving device through intelligent algorithms to support both ready reception and non-ready reception devices. The algorithms work in conjunction with one another to determine the necessary support to successfully transmit fax data from non-internet to non-internet devices via the transport internet mechanism. The method also supports internet originating fax delivery to non-internet receiving devices through use of the same algorithms in determining the support for both ready reception and non-ready reception devices. The method supports phone number validation prior to the fax being transmitted to it targeted destination. The security of the call and transported data is supported by internet security protocols using HTTPS, and security designed algorithms that work in conjunction within this implementation method. Implementation methods fully support all of the FCC E911 emergency regulations that require all user dial tone access points to be fully capable of providing 911 emergency calling capabilities to route to the nearest appropriate Public Safety Answering Point (PSAP).
