442 Expansion Module for IP Phone 1100 Series

The IP Phone 1140E and IP Phone 1150E can also provide up to 36

additional line/feature keys using the Shift key functionality and one

Expansion Module. With more than one Expansion Module connected,

the Shift key functionality does not affect the Expansion Module since the

maximum number of line/feature keys is already available.

The IP Phone 1120E does not support Shift key functionality.
