The M7324 telephone set is best used as a console phone for medium sized to large companies. M7324 has 22 buttons with lights next to each button. This allows the user to have up to 22 lines viewed on the phone. Another good application for the M7324 is to program the extra buttons as other extension numbers. This will allow the M7324 user to see who is on the other phones in the office and to handle calls more efficiently. M7324 is also a two-way speakerphone and can be wall mounted. The M7324 can be expanded to have more line buttons by adding a Key Lamp Module.
