UC-P100-S/UC-P110-S Phones for Skype for Business
Supplemental Guide – DOC. 8412A
Getting Started
What IP Phones Need to Meet
In order to operate in a network successfully, Skype for Business phones require the
following:
•
A working IP network
•
The latest firmware for Skype for Business phones
•
An active and configured Skype for Business server
Initialization Process Overview
The initialization process of the phone is required for network connectivity and operation
of the phone on a local network.
Once the phone is connected to the network via a power over Ethernet (PoE) connection,
the phone begins its initialization process.
During the initialization process, the following events take place:
Load the ROM file
The ROM file resides in the flash memory of the phone and comes preloaded. During
initialization, the phone runs a bootstrap loader that loads and executes the ROM file.
Configure the VLAN
If the phone is connected to a switch, the switch notifies the phone of the VLAN
information defined on the switch (if using LLDP or CDP). The phone can then proceed
with the DHCP request for its network settings (if using DHCP). For more information
on VLAN, refer to “VLAN” on page 44.
Query the DHCP (Dynamic Host Configuration Protocol) Server
The Skype for Business phone is capable of querying a DHCP server. DHCP is enabled on
the 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
The phone’s network parameters must be configured manually if they are not supplied
by the DHCP server. For more information on configuring network parameters manually,
refer to “Configure Network Parameters Manually” on page 28.
