distribution has a zaptel package with the oslec patch (or you build the zaptel
drivers + oslec yourself)</SPAN></DIV>
<DIV dir=ltr align=left><SPAN class=046334806-07052008>Well without echo
cancelation you will probably have a number of calls that have either very bad
sound quality or are simply annoying</SPAN></FONT></DIV>

your set i.e 3-4 lines processing requirments are minimal so you should not
