take into account the cost of the server it would be – how about checking
out the Vdex-40 appliance if you need 4 pots lines or less.</span></font></p>

<p><font size="3" face="Times New Roman"><span style="font-size: 12pt;">I've been looking at various solutions for getting FXS and FXO lines in
and out of asterisk. one solution is using TDM-400 cards. Another
solution is using the grandstream GXW400x and GXW410x gateways. Cost per
port seems lower on the gateways and no pci slot is required. Why would
one choose to use the TDM-400 cards? what would be the advantages and
disadvantages of each approach?<br>
