asterisk users - Mar 2005 - NVBackgroundDetect

Can anybody share information how to install NVBackgroundDetect?

I have the app_nv_backgrounddetect.c but I'm missing:
app_nv_backgrounddetect.o and app_nv_backgrounddetect.so

and have no idea how to generate them.

Wiki point to contact Newman Telecom but all I received was the
app_nv_backgrounddetect.c and no instruction how how to install it.
The installation instruction from wiki doesn't help as I'm missing the
two modules above.

Is anybody using NVBackgroundDetect to detect fax signal on SIP protocol
from ATA?

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.
