Skype for Business phone begins its initialization process.
During the initialization process, the following events take place:
Loading the ROM file
The ROM file resides in the flash memory of the Skype for Business phone. The Skype for
Business phone comes from the factory with a ROM file preloaded. During initialization, the
Skype for Business phone runs a bootstrap loader that loads and executes the ROM file.
Configuring the VLAN
If the Skype for Business phone is connected to a switch, the switch notifies the Skype for
Business phone of the VLAN information defined on the switch (if using LLDP or CDP). The
Skype for Business phone can then proceed with the DHCP request for its network settings (if
using DHCP).
Querying the DHCP (Dynamic Host Configuration Protocol) Server
The Skype for Business phone is capable of querying a DHCP server. DHCP is enabled on the
Skype for Business phone by default. The following network parameters can be obtained from
the DHCP server during initialization:
IP Address

Subnet Mask

Gateway

Primary DNS (Domain Name Server)

Secondary DNS

You need to configure network parameters of the Skype for Business phone manually if any of
them is not supplied by the DHCP server. For more information on configuring network
parameters manually, refer to
Contacting the provisioning server
If the Skype for Business phone is configured to obtain configurations from the provisioning
server, it will connect to the provisioning server and download the configuration file(s) during
startup. The Skype for Business phone will be able to resolve and update configurations written
in the configuration file(s). If the Skype for Business phone does not obtain configurations from
the provisioning server, the Skype for Business phone will use configurations stored in the flash
memory.
Updating firmware
If the access URL of firmware is defined in the configuration file, the Skype for Business phone
will download firmware from the provisioning server. If the MD5 value of the downloaded
firmware file differs from that of the image stored in the flash memory, the Skype for Business
phone will perform a firmware update.
