There are various devices. PCI GSM card, GSM to Ethernet, or the most basic is GSM to analog, then you connect it to asterisk with e.g. X100 card or SPA3000. Either the PCI or Ethernet devices should work very well -- since the call from the GSM network continues to be digital. An analog adapter will have a slower call setup time, can not support SMS or data and might have echo issues and by definition of a digital-to-analog and subsequent analog-to-digital conversion the quality of the call will be worse (but probably not noticeable). Here is one example: http://www.junghanns.net/en/GSM-PCI_produkt.html _______________________________________________ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- asterisk-users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
