Screen Name Not Mine

[MatadorConfusio]

When I call out out Zoon, peope see me and my name below me.  When people call me, my assistant name is below me.  This is formerly her computer.  How can I get incoming to be my name.   Is it a setting on the caller's side.  But it happens to all incoming calls.
