[asterisk-users] echo on TE122

[Ron]

I have setup a asterisk with freepbx, a TE122 and i have an ISDN.
My problem now is that callers are experiencing echo. checked on dmesg i 
saw this:

# dmesg -c
dahdi: Disabled echo canceller NLP because of CED rx detected on channel 2

i searched google but found no soolution and i have no idea what that 
error means.
below are other details that might be of value.
