<h2><a name="news">News</a></h2>
<div class="news-date">Sat Jan 2004: </div> <p class="news-text"><a
href="http://www.stud.uni-hamburg.de/~lennart/projects/ivcall/ivcall-0.3.tar.gz">Version
0.3</a> released, changes include: uucp locking fixes, <tt>ivcall</tt> may listen on wildcard MSNs now.</p>
<div class="news-date">Sun July 27 2003: </div> <p class="news-text"><a
href="http://www.stud.uni-hamburg.de/~lennart/projects/ivcall/ivcall-0.2.tar.gz">Version
0.2</a> released, changes include: many fixes, autoconf support</p>
<h2><a name="overview">Overview</a></h2>
<p><tt>ivcall</tt> is a small utility which may be used to make automated
telephone calls with your <i><a href="http://www.isdn4linux.de/">isdn4linux</a></i> supported ISDN
card. Outgoing calls are
supported as well as incoming calls. The audio data recieved
from the peer is written to STDOUT, audio data read from STDIN
is send to the peer. The audio data is in raw 8 bit uLaw 8 KHz format,
without any headers.</p>
<h2><a name="status">Status</a></h2>
<p>Version @PACKAGE_VERSION@ is stable and feature complete.</p>
<h2><a name="documentation">Documentation</a></h2>
<p>Have a look on the man page <a href="@PACKAGE_URL@ivcall.1.xml"><tt>ivcall(1)</tt></a>. (An XSLT capable browser is required)</p>
<p>You may use <tt>ivcall</tt> as a Unix filter:
<pre>
ivcall LMSN RMSN < IFILE > OFILE
</pre>
<p>Replace <tt>LMSN</tt> by the local MSN and <tt>RMSN</tt> by the MSN
the program shall call. <tt>IFILE</tt> must be a raw uLAW 8 KHz
bytesized file, which is be played to the peer. <tt>OFILE</tT> is the
file the recorded audio data will be written to. It has the same
format as the input file. If no recording (or playback) is desired you
may pipe <tt>STDOUT</tt> (or <tt>STDIN</tt>) to <tt>/dev/null</tt>.
<p>Four detailed usage information try:</p>
<pre>
ivcall --help
</pre>
<p>If you want to create a sample playable with <tt>ivcall</tt> with your
soundcard, you'll need <tt>sox</tt>:</p>
<pre>$ rec -t raw -r 8000 -U -b FILE</pre>
<p>Don't forget to plug in a microphone and set the record volume with
<tt>aumix</tt> or something similar. However, it is recommended to create
audio samples with the telephone itself.</p>
<p>If you have a wave file you want to convert to a sample playable
with <tt>ivcall</tt> use <tt>sox</tt> as well:</p>
<pre>$ sox IFILE -t raw -r 8000 -U -b OFILE</pre>
<h2><a name="requirements">Requirements</a></h2>
<p>A newer Linux Kernel (I think 2.0 is good enough, alltough I tested it
only with 2.4) with a compatible device driver (<tt>isdn4linux</tt>).
<p><tt>ivcall</tt> was developed and tested on Debian GNU/Linux
"testing" from July 2003, it should work on most other Linux
distributions since it uses GNU autoconf for source code configuration.</p>
<h2><a name="installation">Installation</a></h2>
<p>As this package is made with the GNU autotools you should run
<tt>./configure</tt> inside the distribution directory for configuring
the source tree. After that you should run <tt>make</tt> for
compilation and <tt>make install</tt> (as root) for installation of
<tt>ivcall</tt>.</p>
<h2><a name="acks">Acknowledgements</a></h2>
<p>For the developers of <tt>awag</tt> (Stefan Szomraky), <tt>minicom</tt> (Miquel van Smoorenburg) and <tt>vbox</tt> (Michael Herold), since I looked
on their source codes for learning how to use the <tt>isdn4linux</tt> modem emulation</p>
<h2><a name="download">Download</a></h2>
<p>The newest release is always available from <a href="@PACKAGE_URL@">@PACKAGE_URL@</a></p>
