17 WLAN Interface
17.1 Handset Registration
To be able to register to Unite CM, each VoWiFi handset must be programmed with the IP
address of Unite CM used, refer to the Configuration Manual for respective VoWiFi handset.
17.2 Shared Phones
When using shared phones all VoWiFi handsets authenticates with passwords. The
password can be a common password for all users or the call number. Individual passwords
are supported by the User Server in Unite CM.
In order to work, all shared phones in a system need to have the same “major” version in the
software version.
17.3 WLAN System
WLAN system handles the VoWiFi handset relogin time and authentication. A handset is
considered to be logged out if it has not made a relogin within a certain time. Call diversion
display text and Extended activity logging is also enabled in this view.
To find settings for WLAN System, do as follows:
1 Click “Configuration” on the start page.
2 Select Other > Advanced Configuration in the menu on the Configuration page.
3 Click “WLAN System” under WLAN Interface, in the menu on the Advanced
Configuration page.
4 Enter/select the following settings:
• The time before a handset must relogin to Unite CM is set in minutes and when this time
is exceeded the handset will be considered unreachable. This is the maximum time it
takes for a handset to reconnect after installing a new Unite CM or updating a Unite CM.
Note that a short relogin time implies a higher service/security but it also loads the
system.
• Text specified in the “Call Diversion Display Text” text field is, if enabled, added to the
display text when a call diversion takes place. By entering the character “%”, the original
Call ID will be included in the display text on the place where the character is entered.
Note that some characters are special characters that are not visible.
• Enable Extended Activity Log for intermediate logs, for more information refer to the
Function Description, Activity Logging in Unite TD 92341GB.
• The very first time a VoWiFi handset logs in to Unite CM, it must authenticate itself with
a password. The password is then stored in the handset for future authentication. Unite
CM has three authentication alternatives; “Common password”, “User server” and
“Number as password”.
• A common password can be specified in Unite CM and this password is then used for all
VoWiFi handsets in the system. If the common password field is left empty, the handset
must send an empty password for authentication.
If individual passwords are needed, for example for shared phones, passwords can either
be specified in a User Server or the individual call numbers can be used, refer to chapter
4.2 Additional User Settings on page 20.
• Forced login allows a user to login with a call number that already is in use. The handset
that already is logged in will then be unregistered.
