Configuring AastraLink Pro 160 System and Network Parameters
MBU Configuration Download from the AastraLink
The "User List" page indicates that an extension is an MBU handset by listing the
phone type as "Aastra420d". However, handsets will show as disconnected until
the handset has registered to the MBU, and the MBU has been provisioned to use
AastraLink as its configuration server.
You can set the MBU to receive configuration downloads from the AastraLink Pro
by setting the "Configuration Server Address" as the IP address of the
AastraLink, on the "Management Settings" page, and then rebooting the MBU
Refer to the MBU400 documentation for additional details.
Handset Registrations
After adding the MBU and Users in the AastraLink Web UI, provisioning the
MBU to use the AastraLink as its configuration server, and rebooting the MBU,
the MBU will enter service with 420d handsets registered and ready for use.
The MBU Web UI only shows relevant information for the AastraLink Pro for
which it is connected; You can perform all user configuration from the AastraLink
Web UI (for example: Call lists, voicemail, call forward, find-me follow-me, etc.).
