IP Phone 1150E

The Expansion Module is a hardware component that connects to the 
IP Phones and provides additional line appearances and feature keys. 

Up to three Expansion Modules are supported on the IP Phones. With three 
Expansion Modules, the IP Phones provide up to 54 additional line/ feature 
keys.

The IP Phone1140E and IP Phone 1150E can also provide up to 36 additional 
line/feature keys using the Shift key functionality and one Expansion 
Modules. With more than one Expansion Modules connected, the Shift key 
functionality does not affect the Expansion Modules since the maximum 
number of line/feature keys is already available.

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