NaturalFax runs on standard NMS CG, AG, and QX platforms which consist of various telecommunications interfaces, a high-speed controller, and an array of DSPs. NaturalFax supports store-and-forward fax, or the T.37 protocol, which provides a high-performance, low-cost store-and-forward IP fax solution for developers of fax servers and IP media gateways. Real-time fax, or the T.38 protocol, is an upgrade to NaturalFax provided in the Fusion voice- and fax-over-IP solution.
NaturalFax provides a set of document conversion, fax send, fax receive, and fax monitoring functions. A complete fax application also requires initialization, call control (Natural Call Control), and tear down functions which are provided by Natural Access. If the fax application is part of an IVR or unified communications application, Natural Access also provides optional simultaneous voice record and play, H.100 and MVIP switching, conferencing, speech recognition, and text-to-speech functions. This complete, unified programming environment reduces development costs and time to market for a variety of applications.
