We have had some volume and cutting out on our 6X (latest software). When we install systems, we always do LAN Host mode, but we used NAT/Firewall with DMZ on ours to see if any problems would crop up. Today our Frac T-1 was spiking at 1.4 or so (it's rated at 1.5) when we were downloading some programs. During that time, we experienced the voice volume and cut out problems. Our carrier is going to monitor our circuit for a time and get back with us.

Today, we looked at the 6X and the two LAN & WAN lights were going crazy. Much more activity than usual. I don't know if this has anything to do with anything...but we're going to watch it and see what we can find out.

A 6X customer with tons of voice call activity (in & out) has experienced no volume or cut out problems at all since it was installed over a year ago. Neither has anyone else that we know of.
