<DIV><FONT size=2>The questions below don't work for a number of DID
service providers that charge separately for simultaneous calls and DID
numbers.</FONT></DIV>
<DIV><FONT size=2>For example, the Commpartners DID service model charges $x/DID
number and $y/per simultaneous call.</FONT></DIV>
<DIV><FONT size=2>So in a typical residential application you might purchase
only one simultaneous call for every 10 to 20 DID numbers,</FONT></DIV>
<DIV><FONT size=2>while, for something like a prepaid card application you might
want to buy one DID number and 100 simultaneous calls.</FONT></DIV>
<DIV><FONT size=2>Most providers also have a monthly billing
minimum.</FONT></DIV>
