Get an FXO card with hardware echo cancellation. I use the Sangoma A20002D (four FXO ports with echo cancellation). It definitely costs more, but the hardware echo cancellation makes a huge difference in call quality! Software echo cancellation doesn't really work...
With this card, would you say your audio quality is identical to that of an analog phone connected directly to the PSTN? I'm trying to understand if I should expect "some" audio degradation when going through Asterisk. _______________________________________________ --Bandwidth and Colocation provided by Easynews.com -- Asterisk-Users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
