Hi, we have several MVP-210-av units hooked to analog loopstart "CO" lines at remote offices. For the most part the units work OK except for an irratating echo on those lines. I have seen some remarks about MultiTech units and echo problems and was wondering what steps should be taken to get rid of the echo. Our main switch is a 2.1.1 S8500. I keep the firmware up to date.
