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.

Abstract: Systems and methods are disclosed that allow a user to access communications services using a service node or a computer suitably connected to a communications-applications support system at a service provider's facility. The user is provided with information as to the communications services available. These services may be ordered for implementation on and use with the service node or the user's computer or on the computer used in connection with the support system. The implementation and performance of the communications services for the user be monitored, and if substandard, then remedial action may be taken by the system. Also, upgrades, maintenance, and new services may be transferred from the system to the user's computer as appropriate. Advantageously, the user is relieved from provisioning, configuring, maintaining, updating, or educating individuals about these communications services.
