* "Telephony Error" can have a variety of meanings and sources, which are mostly related to the setup of a call. A failure on "telephony error" does not necessarily mean that your fax will never be successfully transmitted. InterFAX records your initial error message and will attempt to route your fax through different servers on different phone lines, which may make subsequent attempts successful.

** "Fax Machine Incompatibility" means that the communication between InterFAX and the recipient did not succeed even though the call was answered by a fax machine. It is possible that some pages or partial pages did go through successfully. Please check for the 'Pages' indicator in the confirmation message that was sent to you.
