latency/jitter unless you can fully interop T.38 across the network. Most
fax machines will auto-negotiate to the lower speeds when needed, but low to
middle end Brother machines may be a major exception as they often have a poor
T.30 implementation.<o:p></o:p></span></p>

<p class=MsoNormal>So the last thread on T38 made me want to start a thread on
FAX over IP via an ATA or something like the Adtran TA900 series.<o:p></o:p></p>
<div>
<p class=MsoNormal><o:p> </o:p></p>
</div>
<div>
<p class=MsoNormal>From our experience, to be most successful w/ FAX over IP of
any sort we've found that if you:<o:p></o:p></p>

<p class=MsoNormal><o:p> </o:p></p>
</div>
<div>
<p class=MsoNormal>1.) Set baud to lowest setting fax can handle<o:p></o:p></p>
</div>
<div>
<p class=MsoNormal>2.) Lower print quality settings if possible<o:p></o:p></p>
</div>
<div>
<p class=MsoNormal>3.) Make sure to force G711<o:p></o:p></p>
</div>
<div>
<p class=MsoNormal>4.) Disable ECM and VAD on fax/modem tone detection<o:p></o:p></p>
</div>
<div>
<p class=MsoNormal><o:p> </o:p></p>
</div>
<div>
<p class=MsoNormal>And then cross your fingers fax's are successful and
consistent. Anyone else have other experiences or suggestions?<o:p></o:p></p>
