I have one in service. It has no serious problems. The one issue we have 
had is that it adds an additional 2-wire to 4-wire hybrid and therefore 
adds an echo source that the remote end hears (varies depending upon 
what you plug into it) - and, I suspect that, because of the somewhat 
longer packet delay, the echo from this source is not well corrected by 
the * echocanceller.
