The line keys on each model are fully programmable. You can set up keys to support either lines, such as directory
numbers, or call features like speed dialing. You can also boost productivity by handling multiple calls for each
directory number, using the multi-call per-line appearance feature. Tri-color LEDs on the line keys support this
feature and make the phone simpler and easy to use.
Fixed function keys on all models give you one-touch access to service, messaging, directory, hold/resume,
transfer, and conference features. A full-duplex speakerphone lets you set up clear multi-party conferences for
flexible, productive collaboration.
