For your particular case, you're probably not going to find much useful info on the wiki about echo cancellation. The info there is about reducing echo when there is an analog-to-digital conversion (in other words, if you're connecting to PSTN lines somewhere). If you have echo on calls that go through your SIP provider, it is possible that they are not doing a very good job with echo cancellation. If the echo is exclusively on these calls, you'll probably want to call them to discuss this. If you have echo on calls between your Astra and/or Snom handsets, you may want check the gain settings on these devices. Reducing the gain would probably lessen the effect of the echo. You may also want to check if either of these phones is doing any AEC (acoustic echo cancellation), and if there are any AEC parameters that are adjustable. I don't have experience with either of these phones, so I can't give you direct info on how to do this, but I'm sure that at least Snom support can help you. - Noah _______________________________________________ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- AstriCon 2008 - September 22 - 25 Phoenix, Arizona Register Now: http://www.astricon.net asterisk-users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
