Abstract
Various methods and systems are provided for real-time facsimile (fax) transmission over a packet network. In one embodiment, among others, a method includes monitoring fax communications across a pass-through connection and controlling transfer of the fax communications to a fax-relay protocol connection based at least in part upon the monitored fax communications. In another embodiment, a method includes monitoring a state of a state machine communicating over a pass-through connection and, responsive to a re-invite to the fax-relay protocol, transferring from the pass-through connection to a fax-relay protocol connection based at least in part upon the state of the state machine.
