It is the remote provider not echo cancelling properly. Think of the echo in this way: what you're hearing is your voice on the remote receiver being picked up by the remote microphone and sent back to you. You might ask your remote party not to use a speakerphone and to press the receiver tightly against his/her ear, as this will dampen the sound detected by the microphone and lessen the echo. -Tilghman ___ 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

If you're getting echo of your own voice, but the remote is getting a clear signal, then Asterisk echo cancellation is working properly. It is the remote provider not echo cancelling properly. I don't buy it. If that were the case then why would I not _also_ get my own voice echoed with a regular phone plugged in to the same POTS line? The X101P cards are notoriously difficult to get decent audio quality out of. I know that when I used mine I tuned it so echo was minimal but the local echo (my own voice) was very fast but (to me) acceptable. I thought it was the FXS card but when I moved and simply did not have the POTS line anymore my local echo went away, with no changes to my phone/FXS card/* server. Conclusion: it was the X101P. You might ask your remote party not to use a speakerphone and to press the receiver tightly against his/her ear, as this will dampen the sound detected by the microphone and lessen the echo. Again I am almost willing to put money on ANY echo problem involving the X101P is the X101P's fault and NOT the POTS line. I say almost because you've been around these lists a lot longer than I have and I still get schooled on a semi-regular basis. :-) Regards, Andrew ___ 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

There is still an echo, but because it's so quickly returned, it's not very noticeable. In the case of going through Asterisk, there is a very slight delay which makes the remote echo noticeable. I'm not sure if the Eastern European countries have upgraded in the past 10 years, but it used to be that if you called from the US to say, Yugoslavia (the specific case in which I noticed this), the party in the US would get a very bad echo. The party in Yugoslavia would hear no echo at all. In local calls within Yugoslavia, because the distance was so short, the echo was not noticeable. But in international calls, the echo was nearly unbearable (especially given the international long distance rates!). Since you couldn't hear the echo in that country, they never knew there was anything wrong. -Tilghman ___ 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

I've replaced the cable, no such luck. Thanks, Jeff From: Deepakumar JV [EMAIL PROTECTED] Reply-To: [EMAIL PROTECTED] To: [EMAIL PROTECTED] Subject: Re: [Asterisk-Users] X100P / Echo / ZTMONITOR CAN2,3, etc. Date: Fri, 13 Feb 2004 07:39:33 - I had similar problems and finally it turned out to be a telephone cable problem that connected from the wallmount to X100P card. But with the same cable i did not have any problem connecting a handset directly (no echo, it was crystal clear). May be try replacing the cable with a good one.

Like a lot of the posts I've seen I've gone through just about every echo can including mark 2, 3, and the steves with the aggressive protection on mark 2. I am running the latest CVS source code that I downloaded late last night, 0.7.2. My echo is really bad on the dialing out line only, the other user has a perfect reception. The inside user has just a horrible echo back of their voice. I've tried various echo canel methods in zapata.conf as well as regular TX/RX gains. I tried running ztmonitor 1 -v and the ztmonitor RX and TX charts came up but did not provide any display back so I was unable to find some better TX/RX. I tried several settings but those didn't help. I am configuring asterisk as a test system and was very happy with the setup until I hit the PSTN. I am hoping the T-1 setup will not have the same issues. Have I missed any steps in reducing my echo? Could my X100P card be prone to echo? Could my line really be this bad (it's not on a regular analog phone)? Can anyone recommend better echo canceling phones? I know this is a frequent topic but I truely have read through all of the past posts from the December echo can upgrade till today.

Re: [Asterisk-Users] X100P / Echo / ZTMONITOR CAN2,3, etc.
I can hear the echo of my own voice as soon as the X100P clicks over to the POTS line to dial the call so I am positive it is not the end party. There is no echo between IP calls across country. As suggested by another user, I've replaced the cabling and tried two seperate POTS lines wired into seperate jacks. I spoke with several people in the digium IRC room who had the same problem and the long and the short of it seemed to be not to use the X100P and either suck it up and do POTS into a channel bank or go straight PRI into a T-1. I just purchased a VoiceTronix 4 port FXO card, I'll report my results on that front once complete.
