Aastra Telecom 57i CT IP Phone manual Softkeys

Depending on how the phone has been configured, the maximum number of total line/call appearances that can be set up is 8 or 9 (4 line/call appearance as hard keys and 4 or 5 as softkeys). If all line/call appearances have been set up for the same number, a total of 9 lines can be configured. If all line/call appearances have been set up between two different numbers, a total of 8 lines can be configured. 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 appearance softkeys may overwrite some of the context dependent soft keys. 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.
