</div></div> The idea with manual call transfer is good, but it's hard to remember<br>
that every time you should ask remote end to press *1 before starting<br>
fax. It's much more<br>
comfortable for everybody to be able use rxfax as a simple FAX<br>
transmitter or<br>
receiver in the middle of a call... There is a demand for that<br>
functionality : )<br>
<br>
With best regards,<br>
