Aastra Telecom 55i IP Phone manual Line Keys, Programmable Keys, and Softkeys

This means that when all line/call appearances are in use, 1 call is connected while the rest are on hold. No further outgoing or incoming calls can be made until one of the line/call appearances becomes available.

In active states, such as ringing, conference, connected, etc., all softkeys disappear except softkeys that have been set up as line/call appearances, and any context dependent softkeys required for the active state, such as the Drop softkey in the connected state. Typically, context dependent softkeys appear in the top left position

and all line/call appearance softkeys appear in the remaining positions.

Note: In some situations, such as during a conference call, the line/call appear- ance softkeys may overwrite some of the context dependent softkeys. In this case, instead of the Previous and Next softkeys, up or down icons,

appear on the display. By using the navigation keys, you can access the same functionality as the Previous and Next softkeys.

You use the Aastra Web UI to set a programmable key or softkey as a line.
