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

[Jeff Stohl]

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.

Thanks,
Jeff
