This is where you enter Phone commands. The top part of the viewport is where the conversation text that you type appears. The lower part of the viewport is where the conversation text that other participants type appears. You can have up to six participants in a phone conversation. Each personengaged in the conversation has a viewport on the screen.
Phone can display as many as six viewports at a time.
The viewport contains information regarding the user's name, the text of the conversation, and various status indicators, such as who is on hold. User names of people that you have on hold can be temporariy eliminated from the screen to make room for new participants. If you are using the Phone utility but are not currently engatged in a conversation, the switchhook character is optional because there is no ambiguity between a command and conversation. When you are engated in a conversation, most of the characters that you type are considered part of that conversation and are sent to each participant. You can enter any Phone utility command during a conversation.
