We have sucessfully "read" incoming DTMF from: a) Nokia32 Analog GSM connected to TDM400 (had to use relaxdtmf with chan_zap) b) Ateus BRI ISDN GSM connected to AVM Fritz (had to patch chan_capi 0.3.5 to support relaxdtmf) Question (I'm from a software eng. background, not telco): What would be the reason for not receiving DTMF from a GSM phone/gateway? Do you have the time to explain why? (I'm really interested in learning :) Thanks, Leandro _______________________________________________ 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
