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>
