Serious problem for user: when the operator (101) is on a call, if another line rings, it only flashes the CO button but doesn't ring. It's a serious handicap; I don't know many people who stare at their phone all the time while on call!

What I've verified/tried:DIL 1 extension and DIL N extension; FW/DND; delayed ringing. Seems pretty basic to me.

If I call each line individually when on-hook, they all ring immediately. If a line rings while on call; the button flashes but starts ringing as soon as I hang up other call.

No voicemail on system


Yes, I'm a frenchie; have a problem with that?? Well, I do!!
