Personally I found the FXO port on the HT-488 to unworkable except as a 
backup for power outages.

I found several problems with it.

1) serious echo issues (I have a long loop).
2) If the phone is answered on the first ring the call goes off to la 
la land.  Explaining to users (or myself) that you need to wait for the 
second audible ring on the handset's before answering isn't acceptable.
3) The device hangs and reboots itself occasionally.

This is all just an FYI.

PS I did test with the latest HT-488 firmware and all issues were still 
present.
