We're using NVBackgroundDetect with SIP and IAX. Several of our products/customers use it successfully -- and in volume. In fact, I think we've only experienced one or two missed detections, which was most likely configuration. For SIP, we've tested all the Sipura (SPA-1000, SPA-1001, SPA-2000, SPA-2100, and SPA-3000), Mediatrix, D-Link, and Linksys adapters. We've tested several providers and * to * configs. No problems. Make sure you follow the wiki instructions for setup and that you understand usage. Link quality, protocol, provider, and mo/do determine that actual fax send/receive results (beyond detection). Great results here as well on send/receive, except on the software side with PDF and TIFF GPL libraries. T.38 and others attempt to solve FOIP, but G711 is working well for most of our clients. The modules have been tested over LAN, DSL, cable, T1, and OC3. DSL and cable worked well, except in some areas cable had problems. In some situations, DSL performance was worse, but generally it was better. BTW- On another note, Cisco recently purchased Sipura. Hopefully they won't kill the company like they have others.
