It provides access to additional features through the interactive soft keys below the display. The M3903 delivers the new productivity-enhancing Call Log feature, which displays a list of the last 10 incoming callers as well as the last five outgoing calls made from your phone.
For added customisation, you can choose to list all incoming calls or just the unanswered calls, and you can instantly redial any call on the lists with a simple keystroke. Fixed feature keys also allow you to switch easily from handset or handsfree to headset use, personalise the phone using the Options list, and quickly access your voice messaging system.
