I have a basic x100p setup and several soft and hard phones that work great until they hit the PSTN. 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.

[Asterisk-Users] X100P / Echo / ZTMONITOR CAN2,3, etc.
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.

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
I've replaced the cable, no such luck.

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.
