Call Appearance/Feature buttons

These 10 buttons are devoted either to handling incoming and outgoing calls (call appearances) and are labeled with the exchange (numbers) and extension number or they can be used as feature buttons to access voice features such as Call Forward or Send All Calls; these are labeled with the feature name. Each of these 10 call appearance/feature buttons has a red light, which indicates the selected line and a green light which indicates the status of that line or feature.

REDIAL button

With the Redial feature, the user can redial the telephone number last dialed from the dial pad. (The handset must be off-hook, or the speaker must be active.) Up to 37 digits can be redialed.
