I have CIX 1200 systems with DKT3210-SD phones. Some of the phones have multiple incoming lines on them. I am being told that when on a call and another line starts to ringing, the user hears the ringing in the handset.

I thought this was a feature that can be shut off. Don’t remember how to do it. Can anyone help?

I have had this in the past and from memory a simple unplug the phone and plug it back in fixed it.

Try msg volume down?
