I have echo problem too: when I call from my OBi110 connected analog phone to some remote party, the remote party would hear their voice being echo back, I will not hear echo on the OBi110 end.

Here is how I fixed the echo problem:
Physical Interfaces > PHONE Port > Port Settings > ChannelTxGain = -5

Try setting the gain to -3 first, but try not to set it to less than -6

The phone I have echo problem with is an AT&T corded speaker phone, I guess AT&T should know a few things about phones I tried a much cheaper Sony corded phone, no problem. Both phones are un-powered.

I guess cordless phones are always powered, so the may be circuitry to isolate the FXO port from the incoming signal?
