I'm getting a slight echo...sometimes...it varies from call-to-call, but the biggest problem I have is a constant hiss in the background. Again, this varies from call-to-call. I know my SIP phones are fine as SIP-to-SIP calls on my LAN work perfectly. I only have problems going out to the PSTN.
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...
I don't know what to suggest about your hiss problem though. - Mike _______________________________________________ --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
