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

[Deepakumar JV]

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.
