Assign Favorites to VVX Expansion Modules
You can assign favorites to line keys on VVX Expansion Modules and automatically call contacts using 
the line keys on the expansion modules. When you assign favorites on your phone, favorites are 
assigned to the next available line key on the expansion module regardless of the index number. You can 
reorder your favorites once they are created by changing the value of their index number.
Procedure
1. Press and hold an available line key on your expansion module.
2. From the Add Contact screen, enter the contact's information, including a unique favorite index, 
and select Save.
VVX 500/501 and 600/601 phones automatically assign a favorite index. The favorite is assigned 
to the next available line on your expansion module and not necessarily the line corresponding to 
the line key you pressed to assign the favorite.
