The 536M provides 36 additional softkeys and can attach to a 6753i, 6755i, 6757i
or 6757i CT. The 560M provides 60 additional softkeys and can attach to a 6755i,
6757i, and 6757i CT.
The expansion modules support the same key functions as the applicable IP Phone
for which it is connected. Each key provides an LED for indicating call status. The
M670i provides a paper label for convenient key labeling, and the M675i provides
an LCD for displaying key labeling.
Note: You use the AastraLink Web UI to configure the additional expansion
module softkeys. For an Administrator phone, refer to Chapter 2, the
section,
“Default Softkeys for Expansion Modules (Administrator or User
Phone)” on page 3-64 for more information. For a User phone, refer to the
AastraLink Pro 160 User Guide.
