Depending on which ESI phone you have, use the appr opriate diagram (below) to connect it. Each diagram represents the panel on the phone’s underside. Note: The “Top of phone” and “Bottom of phone” references in these diagrams show the correct vertical orientation of the phone — i.e., the part with the display is the top.
The common scripts include: “The next available representation will be with you shortly” or simply “We will be with you shortly”. These messages often work best when coupled with expected waiting time announcement.
