I'm not real familiar with the DSU II & Impact phones.

Customer has an 8012 acting like the mute button is pushed. They intercom the front desk but cannot be heard, front desk to them can be heard. They said the hold light is solid and it says call S25. I think we've had this issue before. I assume it's not hardware, but some sort of user error. Is there a reset command for the features? (Like how the dx-80 had F69)
