<div>Even if you find something that claims to be capable of doing this, it will not work reliably. T.38 is a protocol designed specifically to overcome the challenges of faxing over IP networks. Without it, depending on how good of a network and route you have to your ITSP, your results will either be:</div>
<div> </div>
<div>A) won;t work at all due to unpredictable network connections</div>
<div>B) Will work "sometimes" "occasionally" "most of the time" - all of which are not suitable answers in an business environment. It will almost certainly never be "works flawlessly"</div>
<div> </div>
<div>In short, you cannot fax reliably over IP without T.38... you might want to get an additional ITSP account with another provider and use it strictly for faxes. I;m sure there are lots that support T.38, but the only one I know that a friend uses is Gafachi. Your other option is to get a POTS line into your * box, in which case (I believe) Asterisk 1.6 has the ability to act as a T38 Gateway for this purpose. It does not exist without 3rd party modules for 1.4 I believe though... unless somebody has backported all the new T.38 stuff in 1.6.</div>
