pressing an Intercom button and entering a line pool access
code, by entering the feature code and entering a line pool
access code, or by pressing a memory button programmed with
the line pool feature code and a line pool access code.

put on hold or left unanswered on a Private line cannot be picked
up at any telephone except the Prime telephone.
