CS-200, 684, IVC12R12EL, CS-ASC. 14.5.55.30

Went to this place for the third time in 8 months yesterday. The first time there was terrible feedback on all 5 COs. Like the mic gain was cranked up way too high. You can really hear yourself and all background noise through the earpiece. On speaker it just sounds horrible. Ext to Ext OK, and the party on the other end doesn't notice a thing. Checked the COs (TWC Digital phone Arris TM608 MTA), all COs good. Power cycled the system, problem went away.

Six months later, same problem, but only on CO 2. Power cycled again. Issue gone.

Yesterday, same problem CO 1. Contacted ESI, who tried to blame the COs at first, but then made some "adjustments" and had me power cycle again. Of course the problem is gone after the power cycle.

I'm thinking of replacing the 684 the next time it happens. What do you all think?
