</div></div>There are various devices. PCI GSM card, GSM to Ethernet, or the most<br>
basic is GSM to analog, then you connect it to asterisk with e.g. X100<br>
card or SPA3000.<br>
<br>
Either the PCI or Ethernet devices should work very well -- since the<br>
call from the GSM network continues to be digital. An analog adapter<br>
will have a slower call setup time, can not support SMS or data and<br>
might have echo issues and by definition of a digital-to-analog and<br>
subsequent analog-to-digital conversion the quality of the call will<br>
be worse (but probably not noticeable).<br>
<br>
Here is one example: <a href="http://www.junghanns.net/en/GSM-PCI_produkt.html" target="_blank">http://www.junghanns.net/en/GSM-PCI_produkt.html</a><br>
