    Netvanta 7100 and Polycom VVX 400 Phones have internal feedback

      I installed a system about 2 weeks ago, and ever since the customer has been having random feedback issues (they hear people in the same room as them echoing through the handset). I tested this today on site and found the issue happens even when the phone volume is lowered below the halfway point. I'm not sure where to go from here, I've tuned the lines (2 analog trunks) but it didn't help. If I can't figure out a good solution I'm going to try to swap out the unit with a demo unit I have sitting at the office. Any help is appreciated!!!
