I'm hoping there is a solution for this, I have numerous users complaining that they cannot decrease the hands free phone volume to Zero or Very Low. Yet the Volume on the phone display is (00 of 00-12).

Tech support has suggested I adjust the (Maintenance) TDM Gain, TDM Gain P408-418, Index #1 <Load>, DKT-HF, DKT-HF(0-63), to a lower value. It was originally set on 26, but regardless of this setting (0, 5), the phone volume will not go to Zero.

My biggest issue is on All Call/Pages coming over the phone speaker, if the page volume alone could be reduced, it would be helpful. The customer needs the phone page, but not at a high volume as it is.

Any guidance appreciated.
