Firmware for corded system phones

The MiVoice Office 400 application software package contains the software for certain system phones (DSI
and IP), which is updated in each case along with the application software. For other system phones (SIP)
the firmware is located on a firmware server.
The MiVoice 5360 system phones do not have their own memory. All other system phones have a Flash
memory.
SIP system phones
Whenever the phones are started the phone firmware version is compared with the version on the firmware
server. If the versions differ, the firmware is downloaded from the firmware server to the phones.
DSI and IP system phones with Flash memory
The flash memory contains the boot software and the application software. DSI phones also have an area
with the interface software.
The firmware for the phones MiVoice 5370, MiVoice 5380 as well as for all MiVoice 5300 IP series phones
is contained in the MiVoice Office 400 application software package. The firmware versions are compared
when the phones are started. If the versions differ, the firmware is downloaded from the communication
server to the phones. When updating the system software this can take several minutes for each DSI
phone.
The expansion key modules MiVoice M530 and MiVoice M535 also have a flash chip containing firmware.
The update mechanism is the same as the one described above. However a local power supply is always
required (Power over Ethernet is also possible with IP terminals).

Firmware System MiVoice Office 400 DECT

DECT radio units SB-4+, SB-8 and SB-8ANT
The Flash memory on the radio units contains an area that cannot be modified. It is used for starting the
radio unit and receiving the firmware for the radio unit.
The actual firmware for the radio unit is contained in the MiVoice Office 400 application software package.
The loaded firmware is tested when the radio unit starts up. If the loaded firmware is not identical to the
version in the system software, the firmware will be downloaded from the communication server on to the
radio unit and stored in the Flash memory of the radio unit.
Cordless DECT phones of the Mitel 600 DECT family
The firmware for the Mitel 600 DECT cordless phones, is updated via radio (Air-Download). The update
can be enabled or disabled individually for each cordless phone using the menu System - Download server
on the cordless phones. If the cordless phone is logged on to several systems, this menu defines which
system the firmware update is relevant to.
There is only one firmware for the cordless Mitel 600 DECT series phones. It is included in the MiVoice
Office 400 application software package and stored in the file system of the communication server.
