I believe its the "opermode" string that needs to be set to a country. Not sure what values are acceptable, but one google result indicated: opermode=Australia as an example. The driver name for the tdm-fxo card/modules has changed to wctdm, so when you look at those google examples, keep that in mind. I pretty sure you need to do the same thing for the TDM-fxs card. _______________________________________________ Asterisk-Users mailing list [email protected] http://lists.digium.com/mailman/listinfo/asterisk-users To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
