To invoke Phone, choose 6 from the Email main menu. The Phone prompt, also known as the switchhook, is where you enter Phone commands. The top part of the viewing area is where the conversation text that you type appears. The lower part of the viewing area is where the conversation text that other participants type appears. You can have up to six participants in a phone conversation.
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. Usernames of people that you have on hold can be temporarily eliminated from the screen to make room for new participants. If you are using the Phone utility but are not currently engaged in a conversation, the switchhook character is optional because there is no ambiguity between a command and conversation. When you are engaged 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.
