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 soft-
ware 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).

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.
