associated to the user2 account; therefore a new profile is
created.
Not all the information in old profiles is preserved. The preference settings
(for example, voice mail ID) are discarded in the upgrade.
Line keys
Each registered user is associated to a separate line key. Each line key
displays the name of the registered account and some basic state
information for that account.
The primary account is always associated to the first (bottom-right) line
key of the IP Deskphone. If you are a secondary user, the order of the
next available line key is from bottom to top and right to left on the
IP Deskphone, followed by the keys on the Expansion Module from
bottom to top and right to left. You can select a different available line key
for secondary accounts during the login process.
Figure 48 on page 291 shows the IP Deskphone with an Expansion
Module for Avaya 1100 Series IP Deskphones and multiple accounts.
